Starting Short Stacked or Max?

How does everyone else feel about this at the micro levels: .10NL or .25NL

I seem to do the best starting short and playing aggressive with the hands I get. I build stacks up fairly quickly alot of the times. Seems when I get to a mid or high stack at the table, I tend to stagnate. Not win, nor lose all that much. I am starting to think it is a combination of me not wanting to risk as much against a short stack, and some short stacks not gambling with me. So I tend to bank, and start over and continue that trend.

Obviously if the table is mid to high stacked, I start out mid, and start the process. I realize playing short, you are going to cut into potential profit if you get a high stack in a raising/all in war and you werent playing at the max.

I also notice alot of people at these levels buy in at the max, multi table, and are always at right at that level. Seems like they never lose or win all that much.

Anyone else notice this? or have other issues? Does it make sense at these levels to just play as a shortstack and keep banking as you triple up?
