Best Ice/Alpine Pitons?

I'm looking to supplement my rack with some pitons for the upcoming ice season and was wondering which pitons would be best.

I heard rumor that bugaboos and baby angles were the way to go, however my local shop carries Grivel, so specific Grivel pin reccomendations would be nice.

Suggestions? What do YOU use?

i use BD pins, depending on the rock is what i carry, in compact volcanics (ie. camp bird road) i will take KB, Bugs and smaller LA's. In the Canadian Rockies choss pile of limestone (with others) i will take Kb, and bugs (one each usually depending how hard the route is) and larger angles, #2-5 and/or #6.
i dont know anything about grival, sorry. but what to take out of this is that you should carry pins depending on the rock and rock quality and how hard the route is, the harder the route, the more i will carry.
