I have a brand new set of Lanny Bassham's "With Winning in Mind," which consists of 3 CDs, plus a single CD from him called "What Every Skeet Shooter Should Know First About the Mental Game." The skeet disc information can easily be applied to shooting trap. I find this system very helpful, with many good mental exercises to practice to "get into the zone." When purchased as a set, these 4 discs are $57.50 delivered. I have transferred the data to my MP3 player, so I don't really need these discs. I'll sell for $40 shipped.
