Apparently you know nothing about hockey because the Synergy is one of the best sticks on the market. A lot of people would be interested in a used one if it isn't beat to shit.
I go to NMU which is like an hour away from Bohemia. We are expecting snow tomorrow according to the WC. Can't wait. There really are some nice cliffs there and believe it or not there are a few really steep runs.
I have Gold Iridium and VR28 for my Wisdoms. Gold definatly kicks ass for bright conditions but the VR28 is still a little dark for night sessions, late day runs, etc.
If you see what he wrote he skis more on groomers than in the park, so weight is not a really big issue. I'd stick with the Reactor just because I like to keep it all one brand... that's just me though.
The weight is underfoot so the only place you will notice it is in the parking lot. So unless you are a pussy stick with the Reactor. Line skis are "compatable" with other bindings, but you really should get Reactors if you can.
