Personally I've found the quiver to be too narrow across the main body, which makes carrying 2 rods a bit of a tight squeeze and ultimately offering less protection than I'd like. Also with the large outer pocket, if I insert my 30 inch triangular barbel net (complete with stink bag), then the top sticks out and masks the upper velcro straps which hold the rods in place!
In short its about 20% too small and is now used when I'm carrying a single rod only and a hand held spoon net!
Re the Drennan its plain and simple but mine is still going strong after 5 years of use and a regular wipe down. Much more suited to carrying 2 rods than the Korum.
