I’d be interested in this too!
My experience has been that to put bulky lighter stuff in the pulk and heavy smaller stuff in the pack. The leverage of the pulk poles or ropes made maneuvering heavier loads further away from the body much more difficult.
I learned the hard way on a hut trip not to bring more stuff just because you have a pulk. My buddies were like “Jesse’s bringing a sled let’s bring all this stuff.” Bad idea.
