I don't think I ever had a Regina FW. Started with a UO-8, then a Lambert which went SunTour early on, then raced a Fuji Pro and worked in a Fuji/Centurian/SunTour shop. Greased the FW threads with Phil and have never had issues getting them off. (Well, I have had to summon up more leverage and strength a few times. Legs and low gears win over this scrawny upper body.) Only having the first couple of cogs screw on is another feature I like.
