Nbr of Current Games

I've a couple of games going with an opponent that has 364 current games. If I go much over ten or twelve, I lose the feel or character of the individual games, much less, any long term plans or strategies. What have others found to be optimal for number of current games (o/l turn based)?

I personally keep the number right around 7. Doing this I feel helps me to remember lines that I analyzed and to ask myself "Why didn't this line work before? Oh yeah...". If I play too many games I start losing focus on the lines. 

it depend... i normaly only get games wit ppl who hav avg time/move of less than 3 hrs so that means that I only have a few games but they move fast so im havin to make moves at the same frquency as if i had 30 games vs random time/move ppl... nd u can put more concentrate in fewer games.
