I echo neilm's list EXACTLY, he knows what he is talking about folks, IMO!
For only 5, I might drop OLY if you don't play openers or props or halves as they offer no reduced juice at all, and I'd lean to carib for their -102 Tue promo and SIA for dog lines. Bowman's and GameDay have juicy square lines but they disappear fast if you bet the dog/sharp side and they sharp line you - i.e. they deal multiple lines to try to screw the unaware square.
Betaustralia started out with some nice perks and promos but they weeded them out over time and I still prefer canbet whose teaser odds for 2 teamers are excellent.
If Pinnacle isn't in your T5 for almost any major sport, and most minor as well, then you're not very observant or a very astute line shopper, IMHO.
