Raising standards in short-handed LHE

[Hofzinser]

I've recently been playing a lot of short-handed (5 to a table) limit hold 'em, with reasonable success.

However, one aspect of the game which I am not confident about is which hands I should be raising with in the various positions.

At the moment, as a general rule, I'll raise from first position with any pocket pair, any suited ace, kj or higher, a10 or higher, plus j10 and qj suited.

If it's folded to me in the cut off or on the button, then my opening standards are quite a bit looser (obviously all this is very much dependent on who I'm playing with, and I'll frequently adapt all this to suit, but as a genral rule this is what i'll do).

And if I'm in the blinds then I don't like to raise out of position unless I have a premium hand.

Does this seem too tight/too loose? Like I say, I've had success in the game I'm in but I feel I may be leaving some equity on the table as my raising standards are based on, well, 'hunches', rather than anything more rigorously analytic.
