Replying to Problem/Dilemma or w/e

I have 169 PE's that I got last year and I love them but they really arn't that great for jumps. I feel like they are too heavy for me when I jump. I'm not weak I just don't have alot of weight to throw around. I bought used fujatives 159 and they are very short on me. I don't have bindings on them so I was trying to get a pair of 169 or 179's with bindings for cheap. I havn't found a pair yet so should I just keep what I have now and get bindings or try to get some longer skis. I also have found my boots suck so I got new ones which will hopefully help alot.
