Damn, I was hoping you had the 16's cuz I have the 12's in black c17 2.0. Just picked 'em off ebay , they feel real sexy, much better than my Top King SuperStar Air (way too small hand compartment).
Have you tried emailing them? I know from the research I did for a few weeks, the hand compartment size is supposed to be the SAME for brands, and that the OZ. weight in the only difference between say 12oz and 16oz.
However, as you and I may know, a lot of misinformation is pumped out on forums and a lot of people claim at times to feel that the hand compartment gets larger on certain brands as you increase the OZ.
Anywho, I am curious myself so I just emailed them. I reckon 12oz hand compartment size will be the same. Let's see.
May I ask what color your 12oz gloves are in?
