huh?A front on-way with a locked pulley is the same as a front one-way with a center one-way.
A front diff with a center one-way is like a front diff with no front brakes.
I'm sure there's a little more to it than that, but there's no way they "cancel each other out" when they do the same thing (freewheel when over-run). The only possible difference is the slight additional drag of either the belt or the shaft.

That gets another huh?
Zero difference under power on a straight. A center one-way is the same as a locked center under power. A front one-way is the same as any other diff under power on a straight...adding the two together is like adding zero and zero...you still get zero.

A front one-way allows both wheels to freewheel off power but on power will act as a spool except in a turn where the outside wheel freewheels under power since it has to travel further than the inside wheel. The difference between that and a differential is that the one-way will still power the wheel with traction rather than the slipping wheel (think posi-traction).
A center one-way allows you to over/under drive the front end.

When you have a front one-way only, off power the outdrives, CVDs, wheels, etc. spin freely. With both a front and a center one-way, off power the center pulley, front belt, front oneway, outdrives, etc. spin freely. I've found that adding the center oneway allows the whole system to work smoother off power and make the car feel less darty. On power there is no difference.
This is just what i've found from personal experiance, feel free to dispute, flame, call me names, etc. I'm not gonna get into a whole "thing" about this.

I think the information given on this thread is enough for people to understand the dual oneway concept. Just think, is the ground always perfectly smooth like a pane of glass? Is there any guarantee that all four tires will always be the same diameter during the race?

I inclined my front shocks now to get better steering.

when i was using front one way its wide when i m coming out of a turn when powering. When i use dual one way it was wide in & out. Some people tell me its for on power driving some tell me other wise. What is what? I am confused

Front oneway doesn't give you more or increase streering just more corner speed...center oneway to me just more free drag on belt drive...my 2cent

There is a lot of very usefull information posted on the xray site forum about this topic and many others. Xrays top drivers and many others contribute to it. www.teamxray.com
Have a look it is an excellent site.

If your car understeers on power with a front one way, you must have a lot of front droop, try reducing your front droop.
Likewise if your car's not got enough steering off power, try increasing rear droop.

Lemme guess...you're one of those guys who can "feel" 12ga wire in stock? 
I don't know of anyone who runs staggered tires in RC cars...so in that case, I'll have to defer to your specialized knowledge.

Think about it, the front oneway will free up any R/L rpm differences at the front end. However, one wheel up front is still constanly getting power from the center shaft. The center diff also frees up that force, if there is a difference between F/R RPM, resulting in a more free drive train, as far as your tires contact patch to the ground. It is a popular setup in TGP to get the most out of limited power.

There shouldn't be a difference in handling with just the front one way and both one ways.

Then you can also talk about minimizing the rear toe for more topend, and substitute it for the advantages of a one-way setup. Both will give you a twitchy car, but that's your preference.
I don't want to get into wire gauge, since I've seen threads turn into a nuclear meltdown
but it does make a difference in 9T racing. I think it's important for people to try out different setups. One car maybe drivable for you, but a complete monster for others. If it works, great, if not, oh well.

LOL you can deny whatever you want. Everyone has the right to. But getting a higher top speed using a one-way on a low powered car, especially center one-way, is a fact.
