Replying to Hitting jumps switch

Ok this is really bugging me. I have been practicing hitting jumps switch this years and I have a reoccuring problem. I can ski switch really well down pretty much any terrain. I can carve switch really well and I can go really fast switch. However, when it comes to hitting jumps switch half the time I just can't go straight I always end up turning, hook my my tips on the takeoff, and then I don't clear the landing. When I do manage to go straight off of it I can do a switch 180 pretty easy, but i usually land kind of back seat. Anyone had these problems and have ne tips for me?
