Well here is my take on it (I will try to be as unbiased as possible). I have played on party for the last 3 weeks at 10/20. I quit party basically after the monster promo. My results from the last 4 weeks are this

Week 1 +2000 at 10/20 +1800 rakeback
Week 2 -5000 at 10/20 +3700 rakeback
Week 3 +5500 at 10/20 +2100 rakeback
Week 4 +4000 at 10/20 +1900 rakeback
Total +6500 at 10/20 +9500 rakeback

So up 15,000 in my first month there. Its beatable in my opinion (granted my sample size is probably about 25k hands). That being said the games are somewhat harder than party. Truthfully the party 10/20 short games have been getting harder for a long time. I have been playing 10/20 thru 20/40 on party for about 3 years and have seen my winrate slip to the increase in rake and the players getting better from about 2.5bb/100 to 1.2bb/100 in the last 3 years. You obviously can get !@#$#^@$^ from Party on top of that too.

The poster that said that rakeback is like a paycheck is right. At almost any limit you are gonna make more at rakeback than the actual games. But if you go back thru your PT database you will notice that most likely your rake paid to party is equal or more than your win each month there too (unless you are playing higher than 10/20, in that case it really doesnt help you to play at WPEX if you are a 50/100 player for example).
Not trying to be a shill for WPEX just trying to give you guys my experiences over the last month. There is the annoying disconnect problem, the software sucks, and there are only about 5-10 tables each of 1/2 limit up thru 10/20 limit. Also you can only 3 table max. If you have any other questions feel free to PM me.
