250f vs 250 2 stroke for woods and track??

[KDX220R]

I'm 210lbs.--- need a bike to satisify woods/technical trails and mx track.
Should I get a 250f or go 2 stroke 250 and get a flywheel to tone it down for the woods. Riding a KDX220 with mods right now. Don't like the drastic hit on the 250 2 stroke. Concerned that the 250 four stroke my not power my weight. I've been doing more track riding than woods riding of late.
Thanks
