I've heard nothing but good things about CCD. I just stopped by their site and clicked the 'contact us' link. I hope it wasn't too forward, but I wrote them a short note asking them to check out Arboristsite and consider helping to sponsor the site. Perhaps if a few more of us do the same, we might encourage another quality sponsor to join up here.
(Ryan- usually if I want to pass along the website of a non-sponsor, I'll do it in a PM or email)
Back on topic- I rarely use wedges, I prefer to place a rope (tag line) to help pull over a tree or spar. If I need one, I use whatever is available. Been considering adding one to my toolbox, but it would probably just collect dust.
