Replying to Big jumps

ok so im still sketched about spinning off big jumps i can do spins over like small stuff and rails dont bother me but when ever i try to spin off a big jump i speed check a little when i widen my stance and it slows me down, then i land flat and look like a gayper any suggestions on how i should come through this besides sacking up cuz im not intentionally speed checking i just do it cuz off smaller jumps i amost start to spin at the tip of the jump i carve it kinda
