Colossus+ and Multiheaded Template:How many heads can you add?

[Belzbet]

In savage species they offer the multiheaded template to add heads to creatures.

The number of max heads you can add increases depending on the size of the creature as follows:
Up to Medium 1
Large 3
Huge 11
Gargantuan 19
Colossus 29
My question is what would be a good max for a colossus+ creature?
I would say anywhere from 39 to 41 heads max. Does anyone see any problems with this many additional heads?

1) run out of breath mints very quickly

2) hard time deciding what (where & who) to eat

3) optometry appointments take forever

...but seriously, your estimation seems OK. Honestly, I don't think it will impact play all that much.

I can see problems with having only 2 heads.

With that said, the problems I'd see with 2 heads would be the same (or more) with each additional head.
I don't see any problems with your extrapolation of a creature that large having a maximum of 39-41 heads based upon the progression of the other sizes.
