Your forgot the way Bloodlines handled it. Being able to tell what candles contain subweapons or not (well, for the most part in that game it's like that).
Other then that, I only like one sub-weapon at a time. Having all at once complicates things too much. Plus I think it's best when your characters doesn't have an answer for everything with one of over a million moves at their disposal.

I mean, how the heck are you supposed to balance a game like that out? You can't. ... Sadly not enough care or know about this, and thus these type of games have taken over and won today's gamers hearts, to my disappointment.

... I'm kicking myself for having of bought the first 3 Castleroids brand new new now... ... AAHHH! I bought the last 3 Castleroids brand new too within these past 3 months!!

I
am what's wrong with today's games too!!!

... I'm going to go out to see if I can hop over a car as a punishment?... ... back again, dam car just swerved and hit a tree. How lame.
