Working on my Christmas list for Santa, I have a question about four Snap-On ratchets: THNF72 and TNF72. I have never really used a roto ratchet and am not sure which one to get. I am also thinking about FHKF80 and FHCNF72. I have been mainly a chrome handle guy. Any advise? I don't think I will be able to get on a truck to check them out in person, but would like to get one from Santa. Thanks.
