So far this is kind of like "New Coke", but that's why they want us to test drive it.
One feature that 5Dimes has should be copied by other books. They let you make IF bets off of previously made bets ( if not reduced vig), after the original bet was made.
For example if you bet Toronto over 4.5 runs, and they get 5 runs of Mitre in the 1st inning, you could then go back and if bet off of that on something later, and know you have action ( barring a rainout), or chance it if not already a winner.
I know of no other book where you can put in an IF bet, unless you do it at the same time as the 1st bet.
I'm sorry to say that I see nothing extraordinary with this new Phoenix software, but it of course still is buggy.
Phoenix is overall pretty good, their MLB dimeline breaks pretty low at around -135, but at least they have have -105 lines on a fair amount of stuff like NFL,NBA, etc.
I consider them to be a book that I'd recommend. I'd call them top 5, for American players.
