I was in your shoes just 3 years ago. I anti-ed up knowing I was hooked in this sport and demo tested a GOODE ski and Powershell 5 bindings, Also tested a Strada and an A2. I am now on my 3rd GOODE in 3 years, LOVING IT!!!!! And I Practice PB'ed 5 @ 38' OFF at 34.2 MPH yesterday!!!!!!
Now, not to say new equipment will make everything happen, but I was on REALLY POOR EQUIPMENT...... (HO Phantom Truth and Animal Bindings, no speed control, and a 1987 no name inboard ski boat........).
I changed my equipment, boat, speed control, and live on a puddle with a course. That all came together at once and I couldn't see myself going back to anything else.
My 2 cents, demo a ski, nothing but some shipping lost.
You could call Rick @ 1-888-GO-GOODE and see what might work for you if you like the results that 34 MPH skiers seem to have on these skis. You can always send it back if you don't like it, or you find that it doesn't create that "room for growth" that you are thinking it will. For me that was evident when I test rode one, it had room for me to grow.........
