[Closed] Top-pull Road/'Cross Front Mech...?

Right, i've recently got myself a Voodoo Limba 'cross frame, and need a front mech for it. It's got potential for both top & bottom pull mechs but i fancy putting all the cables along the top-tube and out of the mud - i.e. top-pull is y preference.

If i'm running SRAM Shifters, anyone know what my options are for a top-pull 31.8mm band-on front mech? I can't see any road-specific ones and don't know if the MTB ones are compatible with road STi's (and do SRAM and Shimano front mechs use the same cable pull)...
