Personally, I see limit 7 card stud primarily as a game of luck rather than skill. Obviously there is some skill in recognising betting patterns, odds, opportunities, etc, but I don"t think the art of bluffing applies anywhere near as much as it does in NLH. The only time I ever play 7Stud nowadays is in a HORSE tourney, and it"s always noticable how quiet the play goes during this round. Can"t stand the game and would never play it as a ring game. (that said it"s what I grew up on back in the 80s).
The excitement, earning power, control, and enjoyment that I get from NLH, and even Limit Holdem at the right levels, far outweighs Stud..... in my opinion.
