Not many tall WSD choices
Really depends on your inseam vs. torso. If you can ride a 56cm, you have a number of WSD options. If you need a taller frame than that, you really have only a couple choices. I'm 5'10 and all legs (need a 59ish seat tube) so believe me, I've tried. Another custom rider.
Terry has a great trial program and have a couple larger sizes. If you have a good LBS talk to them about getting one of them in to ride. And a few of Trek's road models come in a 58. Haven't ridden one yet, on my list IF I can track one down. Guessing that might not happen. I have yet to find any other stock WSDs in larger than a traditional 56cm size.
But if you really don't need WSD...just test ride the heck out of all the appropriately sized men's bikes, right??
