15/30 raising 1st in?

[TJD]

I have just moved to 15/30 full games. After a long time at 5/10 and 10/20 6 max they seem incredibly tight and rather passive post flop.

I refreshed my memory on limping first in (seemingly a hanging offence at 6 max) and proceeded to play.

My first impression is that the tables are so tight that even an EP raise has a decent chance of stealing the blinds and that if anyone actually HAS a hand then an isolation raise is almost certain if I limp.

This encourages me to limp/reraise more of course [img]/images/graemlins/smile.gif[/img] but also makes limping pretty unattractive on a less than premium hand. I may as well raise to fold the odd hand that is better than mine and steal the blinds to boot.

Have I just hit unusual conditions at this limit or shuld I be open raising if I am going to enter the pot from EP?
