Seat handle height

After long periods of time, i would have to stop riding because i was sitting on my crotch, not my butt. So i put a washer under the front to bolts on the seat to level the rear of the seat more, but now the handle is too high. Will this affect hopping height, should i get another seat (from what ive seen most trials unis have seats where the rear is almost as high as the front)

if you take off the seatpost and you do a 180 turn with it it will be like the other rider you saw, the back as high as the front. Another seat would be the same thing, KH, nimbus, Koxx-one seats all have the same base.
