Here's my take on line bindings... They have an amazing warranty replacement setup... Thats probably about it... Granted I LOVE my line Invaders, and i have had them for 4 seasons so far... First season i had an issue with these so called bindings, i managed to shatter the front of the bindings. Warranty replaced very quickly. Season two: front end of the skis were peeling apart at the tips and splintering, again replaced. End of that season, bindings shot again. Third season went off without a hitch, but my 4th season first day on the mountain shattered bindings. I dont really jib much or hit the rails, i tend to stick to airs. And BIGGGGG airs. The bindings are very cleverly designed, easy to fit to boots if you need to swap em out for new boots, and very easy on the knees with the front and back pivots so that if your heels rotate they will release just like the fronts of normal bindings. This convienience lead to a cheap holding system. I hit a nice little 30 foot kicker landed WAY low, then the next jump in sequence a nice 45 footer, ski and all didnt want to come with me so i ended up bailing out. I would say stay away from the line bindings until the newer generations. you are better off getting a new set of lines without the easy 4 screw mount on the ski and mount a light binding. Oh yeah the bindings weigh a TON. They sit high and weigh way more than the ski itself and im skiing on small 161s. The only way i would recommend these bindings is if you have very bad knees, and dont go big airs. Landing low can lead to some fun trying to land on one ski on the next kicker... Fun fun!
