This is my reasoning as well. I've been doing ED injections for a couple of months now. One of the other big benefits to me is being able to use 1ml syringes and 30g 1/2" needles. 1ml syringes require so much less force to push, and because of this they make the 30g needles usable for me. Keeping that in mind, I think the scar tissue buildup incurred from ed pinning is somewhat mitigated because 30g 1/2" needles don't cause as much tissue trauma as thicker needles, and if I was doing even eod I'd be using a 3ml syringe, which (for me) requires at least a 27g needle. I've literally broke the "wings" off a 3ml syringe trying to push oil before, so I stick to 27 or 25g with 3ml's. I'm addicted to 1ml syringes now, definitely makes my injections much less of a chore.
