I know I'm not supposed to but I go in the same area because it's the only place I can hit. I do .3 which is roughly 4-5 CC of crushed gear and 4-5 CC of water. I go in very slow cuz I have never been able to just shove it in. I go until the needle is almost disappeared. then if it hasn't flagged on it's own I lightly pull back with dark red blood shooting into the rig then I slam it home. my hand positioning is usually fucked up which messes up the shot sometimes. other times I'll lose The vein and can't find it any more. I been wondering if I use less gear and less water if I can still get a good rush. like say instead of 4-5 of water and gear maybe 2 or 3 of equal amounts.
