haha useless generalization indeed.
I had the union forces last year, board got stolen though so they are no more :'(. Got stolen the first day i took my girlfriend snowboarding too, how nice.
Anyways! I didnt care for them =). The toe strap did not have my confidence and it did slip off a little at the beginning but that stopped soon. The screws by the side of the baseplate dug into my boot and tore it a bit, not much nothing to even consider worrying about, but it did annoy me. It was a solid binding though and it's not cheap in feeling. Its fine.
When i tried out my buddy's rome targa bindings (which is a tad stiffer that the 390s) I was amazed at how confortable it was compared to my union forces. This is partly why i'm getting the bosses this year.
Oh by the way triple, i've been reading posts that includde you in it, just wanna say "smile it's snowboarding! YEAH FOR IT!"
