Familiarity: I've used it once or twice and have initial impressions
In the past I have used SNS skating bindings, but now I stick to 3 pins. This is not as hard on my knees as the SNS system with the forward pivot. This ski has given me what I want at an affordable price. I can skate all over the open country here on Cape Cod with the Track Delrin Pinso binding and the Alpina boot with a synthetic upper also available at BackCountry.com.
