Zurai - Just looked at your Shikai (Was checking the thread for new posts, and thankfully now I don't have to do a meaningless bump! *L*)
Anyways, I'm unsure what you're hoping to gain out of your Boost ability. If you're only applying it to your zanpaktou combat array, then the point for point bonus is actually LOOSING you points.
Here's the problem : Normall, boost is used to boost yours AND others powers (You pick 'strength' or 'blast', or some other ability/skill/power), but it still can't raise them beyond their caps. IT's mostly useful for if you (and/or allies) have un-capped powers, so that you can 'boost' them up to the caps. It can also be used to add special abilities that don't affect caps (Such as Impervious to protection, or Penetrating on strike, etc), but for 30, I think you'd actually be better off just buying those powers straight out as the 'enhanced combat ability'. If you were to apply all of those powers straight to your strike & protection you'd be getting all 30 points, PLUS the 1 extra point you had to pay on the boost.
Alternately, you could take the 'personal' flaw (Since the specifics of your boost targeting your zanpaktou array means you could only use it on yourself anyways), reducing the cost to 1/2, meaning you'd pay 16 points for 30 (15 + 1 for PF).
Everyone else - How's them characters coming? We saw a lot of initial interest in this, but seems nobody wants to post a character.
