25g 1" or 25g 1.5"? That makes a big difference!

I use 25g 1" for quads and 23g 1.5" for glutes. Squeezing oil through a 25g 1.5" would take just about forever. (That translates to 4 minutes on my clock.)


As for time, I push the whole thing in at once, in about 10-20 seconds and I don't feel like I am forcing anything...
