I don't think this is brand specific and really fancy clutches (spinlock Power clutch) does help.
However, I jsut received advice on tehis issue from Sailing anarchy-- basically to double up on the cover in teh clutched area using a "nedle splice to marry the two covers. Here is the exchange:

I'd 'needle splice' a second cover into the original...performed correctly the splice is tapered (good through clutches etc) & is renewable
"What is a "needle spice"???
"It's a little hard to explain it in detail but very easy to demonstrate!! Essentially you use a tool to pull the external braid under the existing cover at tapered intervals. You have the external braid (long enough to protect the clutch area) divided into 3-4 unlaid bunches & a small amount of slack in the existing cover. IMO it's the nicest way of dealing with the clutch problem

The hook shaped tools are needles, I've used 1/16 rod with great effect also"
Anybody try this?
