Hi fellas. I'm looking for a 'semi racing' ski for groomers. 171cm 70kg, currently using supershape e-rally 163cm. It's a perfect frontside ski, super fun and versatile with. However when I'm trying to do some high speed mid/long turns, it seems not stiff enough to hold the g force. I tried Nordica FIS SL, it's too demanding and unforgiving... So I'm thinking about some semi race model, such as Head e-race pro 165, Atomic S9 165 / X9 167, Rossignol Hero Elite ST 167. Won't compromise on short turn performance, so GS style skis are off the table. Any comparison and suggestion about this? Thank you!
