My Ambush line, acquired last year, wore out way too soon in comparison to the many I've used over my decades of flyfishing; several inches of the coating have all but disappeared from the head/shooting-line transition. I emailed Wulff asking what's to do, and they responded "send us the line for inspection and we'll advise you of our findings". I offered that if they would send me a replacement up front, then I'd be happy to return the offending line - and that this was important as I'm in the middle of a fishing frenzy (I always am). They came back with "OK it's a deal". The new line is on the way, and if they see evidence that I am at fault I'll owe them. NICE! Kudos to Wulff for handling the matter in a way that assumes I'm honest, and in a way that backs their product performance. Makes me want to support their business.
