First, best binding in you price range: http://www.powder7.com/sale-skis/ski-bindings/New-2009-Head-Mojo-15-Wide-Brake-Ski-Bindings . If you really need the Peak 18 PM me.. but you more than likely don't. Peaks are the best bindings on the market IMO(and all good tyrolias) followed by good sollys like: 914 lab: http://www.skis.com/race-ski-bindings/c435/salomon-914-lab-ski-bindings-p131815.html?utm_source=google&utm_medium=googlebase&utm_campaign=googleproductsearch STH 16(NOT STH 12 or 14), S912/S914 and S916(but the S916s are steel..).
Secondly: Don't mount you Chronics -1. Just trust me on this, you will love them in park way more at -2.5 or -3 than -1. I am not saying this because it is my favored mounti n general, but because mounting CHronics that far up fucks up the flex and sidecut a ton. They just feel bad. Mount at least -2.5 and they will be better than -1..(they were made to be -6(stupid move of line, maby they need to make a " Chronic Park" made for -2) so the flex was made around that mount(much more than a ski like PCs/AR6s/Dumonts) and will feel bad that far up).
