No, Powerlytes are not BOB.
The only "true" BOB body is the Stage 5 (and the Stage 6, from all the rumors and news, etc).
I have a Foehn and I love it...looks great, is light, and is BOB...customer service is great, too. With my Foehn, the only reason I would actually need to take my frame apart from my body is if my eye, QEV, etc. is messed up; and that's like, never, lol.
The "semi"-BOB bodies are the Foehn (
), Strange, and Shocktech.
