The flatter foil perhaps will be less prone to that. I've got some on the way so we'll see what happens when it's fitted. Thanks for that.
Bump!
How did the flatter foil one do, Chris?
Where did you get it from?
Minimine on eBay showed a picture of there fillet strip with the flat foil but when it came it was the convex type when I contacted them they had runout of that type and couldn’t get anymore and forgot to change there EBay picture so I got a refund and was rather disappointed not to get some.
