I sent him my up pipes for mock up 2 years ago with promises of big things. Fleece tested them and didn't find them to perform any better than what was already available on the market for log headers so he abandoned the project. Took several months to get mine back including a wasted trip to his house after I said I was coming to get them and nobody was around when I got there.
Don't get me wrong Leen builds really nice stuff, but I won't be buying it.
