> While it is true that the pulling force is distributed over the entire contact surface, the result is a probably that less stress gets placed on the tunica as one traverses toward the glans on the under the hanger. So a smaller hanger will provide maximal force to a greater percentage of the penile length.<
The only part of that I can agree on with total confidence is the word “probably”. Though if you are wrong, theoretically I could use a 4” hanger on my 5” flaccid and expect the same results as I would with a 2” device.
Beyond this particular discussion I recommend to anyone with a “small” flaccid hang using a home-made Wench that they scale down the 2” dimensions - if anything it will make the hanging process more manageable.
Do a search on “traction wrapping”. You will find good material about improving flaccid hang.
