I noticed Neosteel has two different shaped penis tubes depending on style. The Arch style seems to curve much sharper and underneath. The other style just seems to point straight down. I'm wondering how different they feel and what the pros and cons are of both styles. GWENY...I believe you have both? * Also from reading their site it looks like you can order a belt with different rear shields and switch back and forth from one to the other? I'd love to be able to have both the cable and rear ergo available!
