Side Effect straps

Hey y’all just recently purchased the SE and I love everything about it, except the strap. I don’t love that it is just connected via o-ring and would prefer to use the fabric loops on the side of the bag for the strap. Given this what strap should I buy? Tom Bihn carries several different options but I would imagine that a 3rd party strap could also be used(if there in one with a buckle that would be a huge benefit) Thanks in advance!
