in the short run it will increase your draw odds is my guess; and, in the short run, it could also initially create more pressure on the public ground; it will take a few years for outfitted land to move into the Block Management program, so you could actually have more general draw hunters competing for the same amount of available hunting ground.
It will take a few years for the hunting pressure to even back out over the public ground, Block Management, and private ground.
BUT, as time goes by, it will be a much better program; one of the major flaws of the Block Management program is that it gets the "leftovers" of private ground;
with more funding for BM (which this provides) and the lack of guaranteed tags for the outfitters, over time, more private ground, will be able to enter the BM program, and it will be higher quality ground.
the outfitters got what was coming to them on this one, most of the outfitters/guides in MT are a complete joke.
For the good outfitters, this will actually be a boon because you will get rid of all the 27 yr old punks from Billings, who lease 5 sections of private ground (which locks up 6000 acres of public ground), threatens any hunters who are on public ground legitimately, and has their buddy put together a $100 website, and drives their "clients" around in a 1991 suburban road hunting.
Without the guaranteed tag, these jokers will quickly fade, leaving more business for the legitimate guides.
