GL, Shaka!
Just word of warning.....the +/- 0.5 spread for the 2nd half has always been the "trap" line. Found that majority of the time, the obvious choice is the -0.5 because that team is playing lights out and the opponent seems to have forgotten to show up for the game.
Almost 70% of the time, the +0.5 side will cover.
Just putting this out there.....happens more in college than in the pros, but also shows up the the Association sometimes.....the thinking is you don't want to keep getting embarrassed and will show up to play in the 2nd half.
Again, GL tho!
