H man,
I have only had a few dealings with CS at 5dimes. No problems yet, but others seem to have had a few.
What I guage my opinion on is simple. Let's look at Olympic for a moment. I have seen many complaints about CS, bad phone clerks, and non reduced juice. Even with these complaints, they still made it to the top because of why.......I think it was becuase of a multitude of unique offerings and unique numbers coupled with accepting big bets and paying out big winners without squealing. IMO, 5Dimes is the only book out there right now that is making their unique lines on unique events and aren't scared to take a large wager on their numbers. They are also headed in the right direction in developing a players word of mouth reputation for being financially sound.
So, if you are comparing one of the hundred clone joints out there, then CS would have to be a huge factor (along with reduced juice and bonuses) in your choice of which one to play at.
I want to gamble with a book that has "heart", has unique opportunities, and get paid without a problem. Olympic, Jazz (ABC), and 5 dimes are the books that fit my criteria at the present moment. I understand that what is good for me is not good for all.
