question for fellow SSHE readers

Just curious, for those of you who are using preflop selections along the lines of Miller's SSHE charts, are you using the "tight" or "loose" chart? In particular I'm playing Party's .50/$1 ring games, and I lean more toward the tight chart for most tables, using the number of players/flop as my guide. But do any of you have better results using the looser selections, for example, say you have 4 to each flop and they're playing lost of weak and marginal hands. Just looking for people with more time logged in than myself. Thanks.
