I think low 2900's is a sweet spot for the 109's. I think I can probably get a little more velocity out of my 115s, I just haven't tried yet.
From a wind perspective, the 105gr Hybrid would have to be going 3100fps to match the wind hold of my 115gr DTACs at 2850fps in a 10mph. That speed is pretty easy going for the 6GT and DTAC, whereas 3100fps for the 105 is pushing it pretty hard. You're going to give up some barrel life and load consistency pushing that fast.
Just one reason I lean towards the heavier bullet with this round.
