Keep in mind, the Pivot was their race binding for years, and has remained popular with all sorts of freestyle and big mountain competitors forever. So, yes it has it's following.
Do I think it has some magic to it? No. Which is the P-18 priced as it is. Good all metal housing, single pivot toe....and people will pay that kind of money.
But many do think they are a pain in the neck.
I no longer have any pivots. If they do bring back the 15, I might be inclined to buy a pair or two. On a ski that i wanted to be close to the snow on, minimal weight and one that I might be fussy about flex on. I might. If it's a ski that I might take on and off more frequently. No chance.
I'd recommend that
@Started at 53 try to look at bindings in shop {I know that's logistically tough} and see which he "likes." Very often it's "I like that clunk", or this seems more solid, or easier to get into and out of. Color, too!
Functionally, they all seem to perform. More money gets you more durability in some cases, bigger spring in others. But the heel of the pivots is different. Some love it. Others not so much.
Good post by Matt ^^^^^^.
