XL vs L

Thanks for the comments guys. I've been running 14 cells on the 9L & 10L va an 18.97KWF. I did just recently switch to LiPo, they are the 7.4v Packs so now I'm sending 14.8v of LiPo juice through. I actually felt that the LiPo had more go than my 14 cells did so which would you think - 8XL or 9XL...

Also - Mike C - do you run XL motors or L motors in your beast.

Thanks,
