Bankroll question for SSMTT

[WJL]

I have a question for the esteemed and experienced members of the SSMTT community:

In cash games, it is no great sin to be overrolled, particularly if you are still learning to beat a particular level. For example, if you had a $4000 bankroll, it seems to be better to play at 50NL until you have established success at that level rather than jumping directly into 200NL.

My question for you is this; in terms of bankrolls for SSMTTs, on a $6-700 bankroll, is there a significant enough difference between $1-2 entry tournaments and $5-8 entry tournaments in terms of skill level to justify playing lower at the beginning than I am properly rolled for?

Any advice is greatly appreciated.
