hey, im going to be racing this year for the first time, ive been riding for about 7 months. i ride usually everyday for 2 hrs after skool. ive been to big pits around my area with whoops and small table tops, but not doubles. how do i know how fast i should be going to clear them? if your going to slow on a tabletop, thats diffrend because you land flat, on a double u would case it. are there any tips you guys could give me on aproach speed going off a double in order to clear it, and not case it? Thanks
