Boardman team 2014/15 front mech - what version don't order!?

PJ77

So I've nearly acquired all the bits to get this bike built but I'm stuck on the front mech, I'm going to go with a sram X9 to match the rear, I k ow it's bottom pull - but there seems to be loads of Mount options?? Please could some one shed some light, it's a hard tail.

Both the 2014 Team HT 29er and 650b appear to use a 34.9mm, high clamp.
