With your PBH, you could very likely comfortably ride a 58cm Toyo Atlantis with 700 wheels. The 56cm size with 650b would likely work for you too, but those were produced for such a short period, they are quite hard to come by (I tried for 2-3 years to find one myself to no avail). My PBH is 83, and while I can technically ride a 58cm Toyo, the standover is just a tad high for me to be comfortable on it. I know from experience because I have a couple of friends who are a couple inches taller than me who own 58s, and I have taken them for test rides. For reference, I am 5' 8", and my friends who own 58cm Toyos are both around 5' 10" tall.
