Preferably, anything you can test in-person and you like could be the way to go. With gear being so personal it's hard to make any recomendations. If you like what you tried on in stores maybe you should go with that.
I think it could but ultimately It's how the goalie decides to hold his/her glove that will reflect position.
I hold mine in more of a slighty raised shaking someone's hand glove positioning.
I wish this was released. Who's to say if it will or not, but I remember being so stoked when I first saw this picture a while ago. A Leferve branded C/A would be awesome.
