I agree that the UHFs are a bit too small. I'm just over six feet and weigh 170. I have three large UHF's, each of which is short in the arms and a tad short overall. The XL is too big for me.
My ideal IH Larges are the 07 and the 92 (hickory stripe and hairline duck.) Both fit perfectly. The large UHF's fit closer to a medium in the so-called large size.
