hmmmm - lots to think about there.

Good points on the implied odds Jez. In general of course you'll have bigger implied odds the more that are in - but the point is the implied odds and not the players per se, and as you say the relationship is not as clear as it would be in limit poker.

I tend to play most of my NL (in fact most of my poker) in STT format, so I guess that affects my views, although at the early stages, the differences shouldn't be so stark - bar a few cases.

I like the Sklansky view on this - "Anytime you get an opponent to put money in the pot where he shouldn't, you benefit, anytime you don't - he benefits". We can all agree that (usually - I'll come back to that later) people shouldn't be limping in with K6s - if you don't charge him for this, he is benefitting - if you do charge him and he calls you benefit.
I'd be inclined to the view that if you let in 'suck out' hands then you suffer more than you gain in their loose calls - but that will I suppose depend a lot on your games - it can't be definitive either way. In general though I'd be more worried about hitting a flop like AT3 with my AK and someone else hitting trip 3's or two pair with their AT.

Regarding hands like K6s - in late position (preferably on the button) with several callers these are great hands to limp with IMO, IF (and it is an if) you can happily fold top pair (as you have no kicker). You are looking to make a flush or maybe two pair and someone is likely to pay you off!

Finally as for the raising amount - I'd make two points.
1) In many situations your opponents aren't familiar with you are even don't really watch you that much so it is easy to overplay the deception angle IMO.
2) Assuming you are in a situation where you do need some deception, you can easily do that by varying your raise amounts on ALL hands (e.g. sometimes you might raise 2BB with AK, sometimes up to 8BB) - but your average raise with AK will be bigger. Similarly I'm going to raise bigger (on average) with JJ than I will with AA - as I am (much) more vulnerable and want to play against fewer players.
