Red or any other veteran clampers. I am not getting much pressure anymore from my current clamping routine. I go 5 notches visible. If I go 4 notches it seems too tight at the base and my engorgement level starts to go down. Could I use 2 clamp at 5 notches visible? Right now I had to increase the amount of time clamping to make up for the little pressure but I'd rather go 30 mins tops.
