I know evil mentioned an exotic Japanese custom, a Mizuno Pro Limited was mentioned also. But don't forget to at least check with Bart on a custom Glovesmith to whatever specs you want......for half of the dollar amount you listed. For what you're suggesting to spend you could easily fine someone to check on you a pro-issue Rawlings or Wilson, heck you could buy two Rawlings, two Glovesmiths, or two Wilson customs in different colors, webs, or leathers? Make everyone here jealous!
How about a tough Glovesmith in Duratan with a trap web for rainy bad weather days and a slick custom Pro Preferred Rawlings with a H-web designed to your specs through Chad here? These two will be over $600 but so what if you have to spent an extra $100 or so over with your own money
or get a custom HOH and you'll be about right on the money! I'd make a great politician, I love spending other people's money!
Edit: If I were dead set on spending that $600, I'd definitely buy two gloves from two different manufacturers with two different webs. But that's just me, good luck and have fun with your decision.
