Yep, agreed, Robbie. Anything in the 113-116 range will work just fine with 640X on an Ironman.
On some bikes I've been able to use a 110 but don't think I've ever done that with an Iron.
120 is like Sugino triple territory, but also recall that the 85 Ironman I had several years ago had something in the 123 range for pre-tricolor 6207, which I replaced with a 115.
