9/7 is almost spot on from what Robb described in his guide. I'm doing it in FR and I'm at 7/4/3.5 after around 400 hands at $10NL. I've ran into some real donkeys when I've hit some big hands so I'm running around 33/100ptbb. Anyway, there are way worse things than stacking off when you fill up only to lose to quads. Don't sweat it. Just continue to be Tighty McNitt and you should be fine.

One thing though... you're playing 6-max. If you play FR its much easier to "hide" when you're playing really tight, at least at the small stakes. It's much more noticeable if you're playing shorthanded. Of course if villains have a HUD running they'll be able to tell either way. Me, I don't use it at $10NL. These players are exploitable enough if I just pay attention.
