I dont play the rebuys much but if I do, I play like they're not there. I think add ons are a waste. If your playing well and have 10,000 chips why add on? It looks like 95% use it and I dont see the point. You can make that in 1 good hand so why bother. Maybe if you skip the 1st hour and buy in late with r/a you gotta stack but....
