OK, I'm with you now, thanks. I was aware of the 'natural weapons' line in alter self, but was reading that as being a seperate issue from using those natural weapons in the attack sequence of the form.
Next question: Since I retain my own BAB, does that mean that I use my BAB + STR mod - size mod as the creature's BAB for its primary attack(s) & modify accordingly from there for seconary attack(s) (keeping in mind that I won't have Multiattack; no room for it on my feat selection anyway & easier to just avoid the issue with a DM who's probably going to freak over this build anyway)?
