So, I was comparing the overnight lines in NBA, MLB, and NHL between Pinny and BetIslands.
I found that the vigs for the Run Line, Puck Line, Spread, and Money Line faves were all exactly the same between the two sites. (The vigs for the dogs were obviously worse than Pinny, since Islands spreads lines with more vig than Pinny does.) The vigs on the totals differed some, but the vigs for the lines mentioned above were identical to the cent.
My question is this: How many books actually make their own lines, and how many copy (to whatever degree) another book (Cris, Pinny, whatever)?
Furthermore, and this may not be the proper forum for this question, if Islands is copying Pinny's lines (and it remains to be seen if Islands is just copying openers or is just cloning Pinny all the time), is that one of the reasons they moved to their own facility? I know they were with Jazz before, so it would make sense that now they're "setting their own lines" by just copying Pinny.
