Seeker, sorry for the delayed reply, I was watching the Purdue hoops game.
First off, welcome to the pucks forum, you're not gonna find a better place anywhere else. I have my funds spread out over many places, 2 locals (one's heavy on favs, one's heavy on dogs), 4 offshores (Olympic, GameDay, VIP, Pinnacle). Everyone who's been betting for awhile will tell you that line-shopping is as important as any aspect of successful wagering. All 4 offshore books that I use are solid, have been around awhile and haven't had many complaints about customer service and payouts. At least I haven't had any probs. As far as other books, our fearless leader MadJack, or IE or other guys in this forum will be able to direct you to the books that suit you best.
As far as betting on dogs, you definitely can be successful doing that, but still gotta pick your spots and look at all different angles. It all depends on what style of play suits you best. I happened to like it "doggy style"
. I don't bet on a dog unless I think it has a chance of winning the game outright, that's why I play ML almost all the time. IMHO, over the entire season it's more profitable to take ML than PL. But we also have a handful of incredible cappers here who's record will kick most services' ass, and most of them are fav players.
Hope that answers your question. Good luck!!
