Bob, do you mean the test in "total carp" mag? best performance overall was the aqua cover 10/10(only one with removable lining) @ rrp ?50; trakker, fox, jrc, chub, gardner, tf-gear all 9/10 with chub having lowest rrp of ?30. Jrc was the thickest cover, chub claimed showerproof rather than waterproof.
the shakespeare one they reckon is exc value for money @?28 but only 8/10 for performance.
