I am looking to build a ski from the hull up as a winter project. I found a RXP hull and a ZXI hull, but am definitely still looking. What would you recommend to start with? I want fast hole shot and wwould prefer a 2 seater. I had an Ultra 150 and loved it, but sold it a couple of years ago.I would also like something with some good top speed. Money is an issue currently, but shouldn't be for long. Any input would be appreciated.
