I dont bet much 1st 2nd half stuff myself in hoops but do in NFL. That said I like to have 3-4 outs for it, use Justbet, Bookmaker, 5Dimes and Bovada. Havent really sat down to really look at their lines I go for the best obviously if one doesnt have I am on to the next. My favorite thing about JB is that they have Money Order withdrawls and good bonuses.
Yes you need several books to work with. Just Bet is a must have if you are a football teaser player as they have some I the lowest juice I have found at all levels of teasers...
Sizzle--more tahn one out is a good idea on many fronts. One you may not think of-site downtimes and outages (hurricane/storm season) included. And, most of all, it pays to shop around and even catch a decent middle once in awhile
