Multi-tabling Vs. Step Up

[CardRG]

Not that I’m ready for multi-tabling—I sometimes struggle to hold my own playing one table--but I had a question. I’ve just recently moved up from 1-2 to 2-4 limit. Would multi-tabling two 1-2 tables have been equivalent.

Complexity wise?

Needed bankroll wise?

Potential win wise?

For that matter, what about four 0.25/1.00 tables?

The question is whether multi-tabling a level that you can normally crush a wiser decision than moving up to a single table at a higher level where the opponents may be more ferocious, more wily.
