That MVP series is the one I keep coming back to, although I don't see the GMVP 1159P on their site anymore. I'm guessing it must be a prior years model. I'm assuming the one below is the current 11.5 model. Anybody have any experience with it? Or know how it differs from the prior 1159 model.
MVP Prime GMVP1150PF1 Fastpitch Infield Glove | Mizuno USA
The 1150 is what my DD started out with and it lasted her around 4 years before I bought her a "forever" glove. I had to take a crowbar and pry that Mizuno off her hand when it was time to switch. As far as the differences go between that and the 1159, I can't help you.
