So, I've used my Sync and brought it out against my Geo and FT5 Pro. Sync is definitely an improvement over the Geo in terms of shot, lower weight and I'd say slightly better balance. Still doesn't shoot as good as CCM sticks do though, but closes the gap.
Puck feel is still amazing. I still haven't dialed in if it is more dampened than the Geo, and need a few more skates with it side by side. But every time I use a new CCM stick I question why I loved the Nexus sticks so much... then I go and make a few passes with them and it all comes back. Puck feel is unreal and basically at the other end of the spectrum compared to the Jetspeed, Trigger, and Hyperlite (not saying all of those are the same, Nexus is just way softer).
