What medium sized host for a P7 mod?

Hello,

Well first I was planning on modding my 3D maglite with a P7, but realized that the size would be too big to carry daily (at work).

I read StefanFS' Tiablo A8 P7 mod...and looks very nice. My friend has a Tiablo A9 (knock off), but regardless the size, and shape is just what I am looking for.

I also want a quality light (host), not a "Superfire" or DX/KD low quality light.

What hosts do you recommend for a 2.4a P7 mod, with similar size of the A9? Should I just go with the A9? Do you think the heatsinking would be good enough?

Thanks for any recommendations!
