Ventrogluteal is my goto, never have PIP when I shoot there. A close second are lateral quads (closer to the waist, the higher the better in my experience). I've never shot shoulders or lats, not even sure how I'd be able to shoot lats... I HAVE shot bis, and the PIP is crazy! But the pump when training arms after shooting them is incredible!
Glutes are the worst to shoot, I'm just not flexible enough to twist into a pretzel like that to see what's going on back there.
Then again, I'd probably man up and start shooting shoulders and lats if I were on a ton of gear. Right now I'm running 3cc test e/wk and 3cc deca/wk (750mg test + 750mg deca) and only shooting 2ce a week. But when I was prepping for a show I pinned eod, and i switched between ventroglutes, quads, bis without a problem.
