My starting unpumped girth is 5" (12.7cm) and I want to focus on hopefully increasing that. So I will change devices, but what size tube should I start with?
After an hour (30 min at 1.75x8 and 30 min at 2x8), need to work on getting it worked in more evenly. Was hitting the top of 8 and decided to order a 2.25x9.
