EQ is great for bi and tri shots but I said it before and will say it again, use at least a 1" pin. In my opinion the 5/8 is too short and sometimes with cause a "lumpy" appearence due tot he fact that the injection isnt deep enough and the oil sits on top. Use the 1" and bury it and get that oil nice and deep in the muscle. Again no flames just my opinion and experience.
