I've never played 10NL so I can't compare. I started at 25 since that was the lowest PRoom offered.

What is your raise range when entering a pot? EP/MP I'm raising 85% 6xBB to 15% 8xBB and late position I tone it down to about 50/50 4-6xBB. My range has allowed me to take down a number of blinds pre-flop and get rid of some trash hands that would normally limp in. If I get too many callers in this range I bump it up. I found with a lower range than that I couldn't shake anybody out. After suffering a number of beats (some self-inflicted) I decided to improve my preflop play since I'd rather win some blinds immediately than lose my stack.

The other modification I've made to my game and I'm unsure at this point whether it's much of an improvement overall is to not get cute on the flop. I've stopped trying to set a trap to take a stack since I find I am ensnaring myself more often so until I get a better understanding of the subtleties of the flop I put the hammer down and am more than happy to take a $3-5 pot with a pot size bet. I'll take 4 $5 pots over 1 $20 pot at this point in my game.

Why not just post the ten hands you just listed and see what the locals think.
