obv this method is +ev and profitable. the prob is that it is useless to 99% of us who don't have access to a local bookie who's dumber than mud..

as others have mentioned, this idea is simply a fundamental derivative of the school of line-shopping.

assume this method is freely available, you can likely achieve a more optimal return w/ far less volatility by by taking the -130 side at -110 w/ a local, and selling back the other side +120 on pinny and scalp the 10 cent arb.

of course, if it was that easy everyone would be doing it. not too many of us can find a local w/ a high credit rating who's willing to sell you something worth 130 at 110. which is why everyone is pshawing at your idea..
