I plan on fitting this :-

And driving it with a 7*7135 driver set to 3 mode.
The thermal putty for your a60 is in the same order, but it might be right up your street, and I can always re-order the bits and build another.
I have also just bought a trustfire t2, fitted an xp-g 4c and 1.74a three mode driver, I can tell you it throws as well as my xm-l u2 uf-v3, from a 21mm reflector, I think you can pick one up from fastech for about $16 with whatever the current discount code is.
Tom e has also just got one and is similarly impressed.
