The trouble is with the blinds being low a riase to 60 or 80 chips won't fold out the Axs hands so its hard to know where you are so I prefer a no set / no bet policy (hence the limping) for early rounds, unless of course they beg me to buy the pot

Not saying this is the only way to play, but this works for me. I do think its the best approach if you havn't built up a lot of SnG experiance though.
