Sharing this from Matthew Karatsu - Thanks!
"I have two rollers, a backpack, and the steroid belt and all of them are really well made. I use them almost every day and they have never failed me in the last three years. They fit what I need and are modular so I can change up the configuration when I need to take different gear. Think Tank Photo also supports Sports Shooter Academy, which has been instrumental in my development as a sports photographer. Great products and support of the photography community. Thanks Think Tank Photo"
