SNGs and MTTs -- like ice cream and ketchup

[AtticusFinch]

I've never been much good at multi-tabling, although I've gotten to where I can two-table without too much -EV. But lately I've been mixing and matching SNGs and multis when I two-table. If my results are any indication (I know, low sample size blah blah), this appears to be a very bad idea for me.

I suspect that the two very different mentalities needed for SNGs and MTTs (especially early) just don't mix well.

Has anyone had a similar experience?
