Hi Chris,
Thanks for the reply.
My comment on this proposal would be that if you already have a $500 bankroll (for example), selling 20% would mean getting another $125 giving you a total bankroll of $625.
The difference between a $500 bankroll and a $625 bankroll in terms of managing variance etc is going to be minimal, to the extent that I would recommend you just played off of your own cash.
Looking at the responses so far, I"m sure you will easily have enough interest to get that 20%, you just need to make sure the reasons why you are asking for it. Some players feel they play better when they know others have an interest in their results (less spewy etc.), others use it to get feedback on their play, some want to play slightly higher stakes but aren"t rolled for it at that particular time.
If you have worries about playing with others cash, then I can understand why you have suggested 20%, but if that worries you, then are you going to be playing your optimal game ? No one is going to come on here being critical if it didn"t work out. I"ve had some stalking that has paid off, others that haven"t, and some that are promising good things to come.
