I have relationships, some of which are only available business2business, and unavailable for individuals.
Some went sour and we had to sort of revamp what we did, but many places got their shit back together.
DonBest, of course, but I'm also running scripts on individual sites, allowing to manually check the, what I call, "offered real time lines" which also aren't always offered as you try to trade it and it changes.
Using other tools wrapped around the lines as well. Some other pros have developed services over time that they lay calculators we've devised over the service. Some of that is not available to the public as well.
Also looking at some delayed screens, just to see the market flow. I've used Spanky's tools and even stooped down to using BMR at times to see what it looks like in the delayed public sphere. I'm known to put up the wagertalk odds screen, but that's the only info I get from them. It's not necessary, but I like the thorough layout and who they are showing, even if my friends and colleagues make fun of me...lmao.
I have never really used the new across the street odds for anything, it does have its limits. I used to use classic for a scoreboard and the sound that pinged when line change came through.
Nothing beats my in house analysis though and screens like DonBest are a bit of a must have.
I have some screens created myself, which require constant pinging, and others where info gets pushed to me.
But the B2B stuff is superior. It just is. I can't name all that I use but I can say that I can tap into the odds providers, that's right, the providers, to house like Pinny and others. With that info you can already get a name.
But to tell you anymore, I'd have to kill you.
