Pros and cons of the Canmore Hybrid ( Core-tex & hide) bag, Canmore (Core-tex) bag, to Gannaway hide bag, both with zippers. I have at present a Gannaway hide zippered bag but need to replace because of air leaking around the zipper. ( the bag is 7 years old ) I am just a fun player, for my own enjoyment, do not belong to any bands or groups. I tried listing this on bobdusire forum and am looking for advice. Thank you
