I plan to use it for Racing my Slash but if its a sports pack i think it should be able to handle the pull from a stock slash. OR is it just a bashers Lipo?

Reason: Clarification
They are both hard cased, same 40c rating (so same draw ability). I'm pretty sure the difference is that the more expensive has the "better" cells in it so it gets a touch higher capacity. Its kind of like how all the old NIMH matches would rank and sell different quality cells.
They would work perfect for racing, i wouldn't worry about 200mah, if your worried about not finishing the race caused by lack of capacity get some 28c 6000mah packs
40C pack in a slash is ovr kill... a slash can BARELY pull 10 amps... youll never notice a difference in the slash... only thing youll see a difference in is 1/10 touring car mod class running a 3 turn motor..

I'm not a battery expert,but I know one.And he told me the exact opposite of what you are saying.The two offroad electric classes I run are modified truck and spec Slash.I was informed that I would notice more difference between my 24C and 40C in my Slash than in my brushless T4.Basically because the Slash is much slower,therefore you will be using alot more WOT than the mod truck.I can't say that there is a noticable difference between the two packs,but my lap times have improved slightly with the 40C in the Slash and my mod truck lap times haven't really changed at all since the switch.
There is a noticeable difference between running my 3200 20C Orion LiPo and my 4800 20C Orion LiPo in my Slash (stock spec class).
Same as with my VTA car, I switched from the 4800 20C to an SMC 5000 30C, and the car was definitely faster.
The general rule of thumb is, cram the biggest (highest mAh and C) battery you can fit or legally use in the class.
A 5000 40C WILL be faster and/or retain higher voltage over a 5-minute race compared to, say, the 4800 20C I mentioned that I have, or even over another 5000 except 30C, although the amount may be negligible or not noticeable to most people.
I would consider a "basher's LiPo" to be more designed to have insane run time (like a 6500 mAh) over massive amperage draw.
Just my 2 cents......

for one a slash can only pull 15amps max so it can only pull so much from a lipo increasing the C rating does nothing but making your wallet lighter.. 40C is 180A comtinous I believe....
Thats far from anyhting a slash/vta car could EVER pull... PERIOD...
Of course the SMC is going to be "faster" than the Orion pack... thats like comparing an apple to a pear... SMC is definately the superior pack PEDIOD end of story... the C rating ha dnothing to do with it...
Say you have 2 guys, 1 guy can max out on the bench-press at 300 pounds, the other guy can only max out at 220 pounds.
You have each of them bench-press 150 pounds a given amount of reps. Who will be more tired at the end of the set? Sure, they can BOTH handle the weight and reps, but it will be much easier on the guy who can press 300 pounds because that guy can physically handle more.
Why do you think I said the amount is negligible or not noticeable by most people? I realize that a stock Slash motor won't draw as much as say a superstock brushless motor.
The C rating goes hand in hand with the mAh rating.
4800 @ 20 C = 96
4800 @ 30 C = 144
5000 @ 30 C = 150
5000 @ 40 C = 200
A Titan motor may only draw 12 amps continuous, but that amperage draw spikes considerably every time you jab onto the throttle. So, the 4800 30C will be "faster" than the 4800 20C because the fluctuation in amperage draw won't drain the voltage down near as much simply because the pack can handle more.
Out of the 4 "packs" I listed, the 5000 40C would come off the track after 5 minutes at a higher voltage than the others, which means it retained a higher average voltage over the entire 5 minutes. More volts = more speed.
Which is why I said, just cram the largest/highest rated pack you can into the vehicle.

You won't get literally twice the run time, but if for instance you have a LiPo cutoff set at 6.4 V, you may get a little more time out of the battery because the amperage draw isn't such a strain on it.
Of course it makes sense to save $40 if you aren't worried about those few tenths of a volt that the extra 10C may save you, especially for just bashing. In racing, however, every tenth of a volt helps
I may actually look into that 6000 if you're getting 45-minute run times

Tenth scale off road trucks, buggies, 4wd's with the typical applications will never draw close to enough amps for anyone to worry about maxing out there C rating.
The higher C rated packs are more aimed at the needs of the HV combos that are in 1/8 applications.
Its best to buy what you can afford, in a good quality pack.

I sorta agree with you,but I think that if you are buying a ROAR approved lipo that you are most likely using it for racing.And even though the Slash trucks have pretty slow brushed motors,having the higher C rated pack will be an advantage when everyone is running the same electronics.Think about it,if you had to race in an out-of-the-box spec class,wouldn't you want the absolute best battery you could get?IMO it's one of the only advantages you can have in a class like that.
whats the difference between these two SMC packs?
