Several weeks back, I ordered the "All-in-One" suspension from whoopieslings.com. Smokebait was very responsive and answered a lot of technical questions with which I pratically assaulted him. In the end, I decided to purchase seperate slings and straps not at all as a comment on the quality of the AiO system but more on my personal preferences. Even so, I ordered those also from Smokebait and he was again extremely accomodating. Big thumbs up for the help!!!
