Honestly I trust Volcoms High-end Gore more than Burtons. Frozen glove tips usually means that the tips got moist. Typical actually since that is where the most wear is going to be happening. Only thing you can do really is to get the appropriate water-proofer and re-apply as necessary.
True about circulation playing a big role in how gloves work. Joey Sex probably has really good circulation to his hand cause he says he doesn't even wear gloves. I also know people that have lukewarm hands wearing mitts with handwarmers in late Feb. So it definitely helps to know you're circulation. If yours is average or better, worry more about core and less about the "tech" in your gloves. If its less than average then I would make sure you get gloves with handwarmer slots or mitts.
