This and This.
The DLX highback has a similar shape as the contacts but in no way are the flexes similar. The contact highback is pretty soft, to the point where, even with the forward lean cranked, it felt like there was nothing back there, or that it had folded.
DLX is an awesome binding for the price, and are fine for all mountain and park. Regular Contacts...for me, not so much.
I think you're right. The DLX from last year was exactly the same as last year's Contact highback (now this year's DLX highback), except the Contact highback had 2 more spaces milled out in the center. This would have made it softer, but I didn't think there would have been that much of a difference.
Since this can be a little confusing for anyone else reading who hasn't yet seen the difference...it's picture time!
"Do you see what I see?...
...Do you know what I know?"
Well, now everyone definitely does.
