Mountaineer, a.k.a The Mountain, a.k.a Mountain Welfare offers $0.50 supers. I've hit quite a few of them and the payouts can be hefty if you wheel them properly (boxing is for rookies). Some obvious angles I've noticed is Deshawn Parker & Oswalda Pereira get the good mounts, deservedly so. However, they are over bet which creates an opportunity. Next, the 50 centers are best played on 5 to 6.5 furlong races, too much can go wrong in a mile and up. Third, only bet the 50 centers on a 6 to 8 horse field. Forth, don't be afraid to put the bombs on top and for 4th place key in some mega bomb closer types 20-1 & up. Typical wager ranges from $3.50 to $9.00. The templates which I've had success with include:
Key the Heavy Fav: 1 with 2,3,4 with 2,3,4 with 2,3,4,5,6 (2 & 3 are semi-bombs 8-1 & up , 4 is 2nd choice, 5 & 6 are those good for nothing's that hit 4th place randomly but have mega odds, 20-1 & up). This wager would cost $9.00.
Key Heavy Fav in Second: 2,3,4 with 1 with 2,3,4 with 2,3,4,5,6 is $9.00 as well.
2 Bombs/2Favs/2 Bombs1Fav/1Fav2 Bombs1good for nothing: 2,3 with 1,4 with 1,2,3 with 2,3,4,5 is $5.00. This template I've had the most success with. You can use different variations of it as well, eg. Bomb with Semi-Bomb with Fav with Bomb. Just key the Fav in 3rd.
