Default Lipo vs Nimh Racing and Minimum Weight

for those who want to run Lipos- do you think its fair that if you want to run, say an Orion 4800mah pack, and your car weighs in at 1275g (ex:Yok BD w/ 4800 pack weighs around 1275 rtr) with that pack, and its 7.4v, of course....and you're racing against others who prefer the 6 cell nimh packs, and they are running 6 cells at 1.3v each for a total of 7.8v, but their car weighs in at 1550g, due to the extra nimh pack weight...Here's the catch...those running the NIMH matched cells demand that you run your lipo equiped car at their class's minimum weight limit of 1500g...is that fair? If you now have to run at their weight of 1500g, wouldnt that extra 125g of lead you'll need to add to your car to meet weight decrease your cars performance and put you at a power and speed disadvantage when racing a NIMH equiped car using recent pro matched cells? You'll be running your Lipo at 7.4V @1500g, but they'll be running 7.8V with the current pro matched cells and have more punch and power that our Lipos? Is that fair? Maybe those that run Lipo can run at 4-5 cell nimh weight and thus make it more fair to run against the 6 cell powered cars? That would mean 2 weight limits for each battery type. Or maybe limit the power on the 6 cell nimh so its at 7.4V, like the Lipo? We are trying to sort this out at our club races coming up and would like to know what you all think...it gets even trickier for those running 5 cells...then what?
