Guys, I need a new pair of pacs. The ol LaCrosse All-Temps are done. I'm thinking Schnee's but I'm open to suggestions. Need to have a waterproof rubber bottom, leather upper and lots of insulation for deep snow and cold temps. (I sometimes go calling coyotes at -20) Let 'er rip with your experiences. If you've got a brand to stay away from, let me know why, too. Thanks!
