Wildcountry Syncro Question and Harness Advice

I'm retiring my beloved Wild Country Syncro S Harness and am considering buying the new model, but there's no where around me where I can check it out in person. Is there anyone out there that has climbed in this thing? My only gripe with this harness is the difficulty of operating the ziploc buckles. Has this been improved at all?

I've also come across the Wild Country Summit in my search. How does this compare, and do they even make that harness any longer?

I am open to other suggestions, with a few caveats as well. I am forever stuck between a small and a medium in most company's offerings, so having twin buckles on the waistband is critical, and adjustable leg loops are pretty necessary as well. 6+ gear loops is a must as well!
