thanks WS for sharing your work...
to shack: i think WS says that in his second set of plays he increased the unit size from one to two. I believe that is the only difference
and another poster pointed out that WS thought that playing his totals to -130 would be worth it...personally, i would never buy off a number such as 8 to 7.5 but would feel comfortable buying down from 8.5 to 8 if the juice was too high.
good luck
