Well ok, I think my main concern is about the possibility of being a good winner without multitabling and spending just reasonable amount of time playing. Seems it is possible
Some things I start to miss when multitabling are related to my mt-skill/concentration I beleive, like I can forget what were my several previous actions at one particular table. That might be correctable. The main thing I see now is I can't track villain timing tells, i.e. he acts while I'm busy on another table, and when I switch the only thing I see is a result, but do not have that "feeling of the moment" of how long did it take him to make a decision...
