I did Tricks late December 1997. We bivied midway up, in the terraces, then on the summit. Short days, cold morning starts. Day 3 we descended the very snowy north face to the slot canyon between Isaac and Jacob (took all day). We each had a very lightly-packed A5 Grade V haulbag. We hauled the bags together for most of the route, but on some of the lower chimneys jugged with them. Not as bad as it sounds, but not that great either. We also each climbed with our bag on our backs through portions of the terraces. That was as bad as it sounds, but better than hauling there. The key was going light.
Hauling the lower pitches was no problem this November, we brought a BD stubby and clipped a gallon to the bottom. Whomever is seconding can help the pig in a few sections. A 70L filled halfway would probably be ideal.
Watch out for a big block ontop the calvinator just under the anchors. It was the "ledge" we were hauling from and collapsed when we were trying to get the pig over the lip, and core shot our lead line... Apparently you can rap the entire route now, negating the need to haul the headwall and carry over (which sounds epic and fun in a sick way). Bivy low on the terraces and avoid hauling/humping the 3rd class.
