When I had curves on my attak...I was told you couldn't use ANY dually type carbides (slim jims, deuce bars...etc)...Did something change?? They had some kit you could buy to eliminate darting (can't remember what it was called)...the "cheapest" solution to eliminate darting has always been to use stock skiis, shims, and any dually type carbide (or triple points)...You will get opinions all over the place on here on this topic ...but if you only ride trails, and aren't super aggressive...this will work for you.
The curves are a quality product...they look nice...but IMO...they are a better ski for aggressive riders, ditch bangers, and 50/50 on and off trail
