Help with new board

I currently ride a Phase 5 Prop board. I bought it a couple of years ago and dont think it is the right board for me. I am 200 lbs and over 6 feet tall. I have an xstar with a decent surf wake. I can stay behind the boat without the rope but am usually within 1-2 feet from the platform and struggle the entire time staying there. My 150lb buddy recently rode my board and rode further out and rode with ease. I watch all these videos and just think I need a different board. I am a pretty decent rider but need a suggestion on a new board. The Phase 5 was expensive enough and I dont really want to spend that much on a new board. What is the best board for the money? Anyone want to buy a nice Phase 5 Prop or trade me??
