I shoot Lats all the time Ozz..... I usually grab the doorway, look in the mirror, and shoot right into the center of the Lat, but towards the back as much as I can reach..... The Lat is pretty Fiberous, kinda like the Quad, so be prepared to push a lil harder.... I use 1 inch needle, but 1.5 can be burried there too..... I will say, if you shoot Prop in there, and it's gonna be sore.... It hurts like a bitch...... Never hit a nerve or vein in there, so it's a pretty good location IMO..... Pecs are my new favorite injection spot though....
