raising < pot PF

[TheSeeker03]

at a full ring table with 10 players and 100BB stacks, is there a time you want to raise less than the Pot pre-flop?

I play lowest stakes and like to build pots in position. When I have something like A578 w/ suited Ace I would raise to 4BB after 4 or 5 limpers. My thinking was that I don't want anyone to fold by raising pot because only hands with equity similar to mine will stay, while hands with low equities will fold, making my equity vs. competition lower.

So I had 2 raising modes when in position:

1. THE POT. reserved for very strong hands. I am most likely to have the highest equity, so I want to make the biggest pot.

2. SWEETNER. What every limper is guaranteed to call based on my observation of the table. This mode is reserved for hands that have better than average limper's equity, but not great.

Aside from being less predictable, should I get rid of the SWEETNER option, and just raise the pot all the time I have a raising hand in position?
