I'm also a HH user...i have the Deluxe explorer...I'm 6'0 220 and i'll tell you what i do appreciate the extra room. I thought about the smaller size due to weight savings but the freedom I get from having such extra space is worth the few extra ounces. Did you get the classic entry or the Zip model? Big difference there as well. Good luck with your new gear...you'll love it.
I purchased the classic bottom entry. What is the big difference? The bottom entry sounds very neat.
