Agree with Ant the Dinsmores have lasted well over 6 years and the only reason I need to change one is I caught the top ring on a fishery platform fitting and it sliced a slit in it.
The material has been the best carp friendly one I’ve seen used. The others with larger holes very often snag fish on the dorsal fin and leave them hanging. Not good for the fish and not good for the net.
This is not one of those buy cheap pay dear situations, but then you don’t have all those pretty graphics to pay for on the top ring.
