In reply to echo34:
At those grades, any of them will work.
So pick one that "feels" right. If you wish to have financial support, look into pick prices and how easy they are to obtain.
AFAIK EClimbs and CTs aren't that widely available... so you need to keep spares on trips and such. BDs are quite commonly available around.
Oh, and I'd also look into aftermarket picks. Krukonogis (krukonogi.com) are stellar for alpine & mixed, but spendy. Polish Kuznia (
https://kuzniaszpeju.pl/pl/) are a lot cheaper, and almost as robust as Krukos.
I'd prolly pick the new Vipers, but that is mainly due to the fact that my household already has 3 pairs of BDs and they all share the picks...
