The B means special design. They should be fine

I would do a search on the cr10's. There are a lot of mixed reviews out there. Some guys say that they get more horse power (by the seat of their pants testing). I remember reading one post I believe it was from Hurricane Performance (not 100%sure) that said they tested on the dyno for 1-2hp loss.
From what I remember after reading a lot of posts is they don't seem to run as well in colder temps (10 being a colder plug), some stories of fouling. But most of the posts that say that they are great seem to come from warmer riding areas.
For myself I decided that the stock plugs are less hastle and I never want to be wrenching when I should be riding. Do a search and decide for yourself.
