New golf irons advice?

I'm looking to get new irons to replace my old Mizuno MX900 irons. I've narrowed my search down to 3 sets of irons after a few trips to the local Edwin Watts and their simulator. The three sets I've narrowed my search down to are the Adams CB2 black irons, the Titleist AP1s, and the Cleveland CG16s. I hit the 6 iron demo well with all three but am more concerned about the long irons as they don't have them to try. My average round is anywhere from an 80 to 100 depending on the day. I'm looking for irons that will consistently help me keep the ball straight as I tend to push the ball to the right. Any advice from golfers who have played or demo'd any or all of these irons would be greatly appreciated. Thanks!
