I dont use the bm or pump for expressive, it just doesn't provide the angle I want to work with.
Using the lengthmaster provides that, and it gets confusing due to all these other names it apparently had in the past, like hole stretching which I never heard about? and just sounds to me like a two handed expressive stretch.
All you do, get a LM or PA, and put the entire package through, has to be everything. Than, it is stretched DOWNWARDS over the loop, not up, just downwards, and it just seems some guys do whatever next to provide the force. Your trying to stretch that entire area right at the extreme base.
Also getting pix or videos is mega hard due to needing both hands, and the positioning. DLD had a diagram once but it has gone.
