CMSU has a good program from what I hear, but we are not familiar with their camp. I know of a few players that have played with them or are doing so now and have heard good things about the program. They had some good pitching this past year.
KU is an up and coming program under the guidance of Coach Ritchie Price, who is a first class individual. Coach Price previously took Cal-Poy from a D-2 Program to a D-1 Program. He is instituting big upgrades and improvments to the facilities at KU. KU is a good academic school and Lawrence is a nice town. Coach Price has done a lot of positive things with the program.
It is my understanding that Coach Price has somewhat modeled his camp after the Stanford camp. The similarity being that Coach Price has other schools in attendance, beside just KU. I'd double-check this because we've been out of the recruiting thing for a couple of years. But it was my understanding that there are several schools in attendance, if that is the case you could get more bang for your buck so to speak.
