I am at a loss when it comes to selecting a boot for a sprung conversion with a similar fit to my 8D AC3 skates that I very much like. I just can't see these missions staying stiff with the hours I put on skates. I skate 5 days a week(rec skating ref, and league play) so ice boot durability is a very attractive. My primary concern is with depth. The high end AC line seem to have lots of volume and I am not sure what ice boots will give a similar fit. Which $200-450 skate would make the best platform and provide similar fit? So tempted by the 14ks, supremes, or some Grafs.
