Well, I've decided it's worth it to buy some gear instead of renting it, been looking for deals for awhile. I found some brand new Dynastar Concept Twin Tip 178cm skis, although they are a few years old (here's a picture and another). The store is willing to let them go for $100, and I have the option of getting some Marker bindings with mounting for $90 (don't remember the model). Not that related, but I have Salomon Mission 5 boots (25.5).
I'm 5' 9" and around 70 kg (155 lbs). I'm honestly not sure what level of a skier I am; went downhill skiing for the first time last year at Mont Tremblant and by the end of the weekend I was quite comfortable on the black diamonds there... So I guess that's around intermediate? I'm probably not going to be in the park, but skiing switch looks fun which is why I want twin tips.
Should I go for them? I told the store owner I'd get back to him tomorrow; as of now I'm thinking of getting them. Thoughts and suggestions?
