Thank you mark, what about the turn radius on the groomers? Does it feel like you are riding a mid-fat, or is it still comfortable? I'm still in doubt between TST and turbo. The TST has a small radius which is nice for moguls etc.

Yeah - if you're looking for a small radius then you may prefer the TST. The Turbo is a medium radius ski and would be more work in the bumps. For groomers, however, it will lay a trench with ease due to the stiffness. Feels like a mid fat for sure - but it seems like everything is a mid fat now. If you are on the east coast the Turbo would be a great fat ski, if out west then a great daily driver. If you ask the same question over on the TST page perhaps you can get more insight from someone who has spent more time on that ski than I have.
