I am using Thome in an 80M league and actually started him as a platoon, but the Platoon wasn't working as well. For just over a week, I used him strictly against RHP and he belted out 17 HR's and was batting nearly .350,
Now having him go both ways and his average has dropped to around .290, but has hit 4 Homers vs Lefty pitching, so I won't be using him in platoon any more.
He is worth the money IMO if your team is slanted towards left handed side as mine was and needed the Hard Righty bat.
