Are you particularly fussed on composting it, or do you just want it off the trails? I feel that raking then picking up with the FEL is likely to fail, or to be so fiddly as to be infuriating.
But if you just want the trails cleared, rather than particularly want to accumulate the debris and make compost, then perhaps a large blower would be a better investment? Just blow the trails clear, and done. I can see that being a much easier process.
Thinking further on that, perhaps it is a bit like my lawn mowing. I really dislike collecting clippings, so I mulch. I always say I'd rather mow twice mulching than mow once and have to run a bagger. And when you mulch you definitely have to mow more often. So perhaps the answer on your trails is to mow more frequently, rather than collect the debris? A trail mowed more often will look tidy even if you don't collect the debris, because it won't leave big clumps everywhere. At least, in my mind that's true, I don't actually have trails that I mow.
