Always complete the Small Blind early??

[anatta]

I have only played about 30 of the $20 SNG at Star and I have a question...

Early on I am looking for players who play tight, maybe they won't defend their blinds. If the blinds are 10-20 and I see someone fold their small blind, I mark them as a possible tightie. I would think in big bet poker completing with any two at this point would be +EV anyways, coupled with the fact that its important to make a first impression I have concluded that I shouldnt ever fold here. ??
