Thanks, guys.
Yes, bumpfreaq, I was a bit worried that the bindings might be a bit "undersized" for me although the charts only put my DIN at 8, even if I lie a couple years about my age...with a big boot (345 mm) the DIN settings end up being lighter than you'd expect.
My kids are still young (6 & 8), but I hadn't thought about keeping the binding for one of them. My oldest will be 9 in Dec, so it might be right for her.
I did a bit more research late last night and I know the HD was made specifically for CMH. There aren't a lot of reviews of it, but I think it's a bit softer than the SD and it is lighter, so a 190 is probably a good length. The next shorter size is a 180 and I would think that would be too short.
For 250 I can't complain and if I don't like them, I can always sell or trade them here, right?
Enjoy your summer!
