TNT, I also get the bulb. I’ve noticed that it is very pronounced when I start soft and work my way up. How much have you gained from clamping? Dustpan and drilla, both with very considerable girth gains start hard then clamp. I’m curious to see how many people that do it the other way have made good gains. I would guess that most people start hard since that’s the way it tends to be described in the “how to” threads.
Keep ‘em coming.
