damn man how much leakage do you guys get? i mean i never get any leakage i just push in slowly then as i pull out, i get right near the tip, and leave it for about 3 or 4 seconds then pull out and i never get any leakage at all. if you guys get more than a drop or 2 i would be surprised. let alone unless you are leaving air in your syringe at the top you are also leaving gear behind in your syringe so whats the difference. and i only pin my glutes and delts and i dont think i can ztrack my own glute shot. so yes to me its not worth it. i know it takes no more time or effort to pull skin down to do a ztrack its not like its rocket science. thats the only difference in a ztrack.......
