What up my man. You look freakin awesome!!! If your trying to widen that back for more V-taper you need to be doing weighted wide grip pullups. Lat pulldowns are NOT a substitute for wide grip pullups. What helped me begin my V-taper was barbell rows and since I got back into the wide grips by back as widen out significantly. Tryed to the lat pulldowns and it does not work anywhere near as well as old fashioned pullups, wide grip that is. But thats just my two cents.
