I play shortstop, and out of those options, i'd go with an 11.5, I-Web Wilson A2K. Personally, I play with Mizuno gloves. Mizuno seems to specialize in gloves, baseball-wise. But out of your choices, Heart of the Hide gloves seem to be lower grade leather then the Pro Preferred. I've had Wilson gloves in the past, and they hold up well-just as good as Rawlings. The A2000 is an older model considering that Wilson came out with the A2K not long ago, and that's a good model. As for webbing, trapeeze is more of an outfielder's webbing since it's closed; 2 Peice Webs tend to get loose easily; but I-Webs are sturdy and made for infielders. Size is optional, but i'd stick with 11.5. 11.25 tends to get too small, and is more for a second baseman. 11.75 is usually made for third baseman. Gloves are real expensive now, so choose wisely.
Hope this helps.
