I am not going to claim any expertise, but I did GM my hiding by putting it on the spacebar... it can be disconcerting sometimes when you are talking to someone, but it makes for good steady gain. Bought the original, then worked it from the bought amount. Stealth is slow though, but it'll get there. Wore Leather armor the whole distance. When not talking, I would just hit the spacebar now and then to keep it going.... kinda like dancing the keys lol..
