I am 55 yrs old. I've been skiing on an HO VTX 9.8 flex slalom ski for 30 years or so. Either it's getting heavier or I am. I tried out a brand new D3 and it was complete opposite of what I knew. Almost too light; too fast. What would be a good step up from what I'm on. It's a 66 and I can make 15 off with it but don't ski a course usually. Need recommendations.
