Has anyone tried the new Redmax bump feed head. I saw one at the GIE. I was real excited because it looked like the Green Machine head with a couple of improvements. THe bump button had a metal rod in it so it wouldn't wear as quickly. Also, the eyelets were replaceable and I think the spool had a divider down the middle to keep the two strings separated. I have always like the Green Machine heads because they cut nicely and aren't too sensitive on the bumping. I have a couple of shindaiwa bump heads and they feed so quickly on small bumping (like when you are trying to get under a bush) that I can run a spool out in just a few minutes even with 0.095 line. It doesn't wear that quickly, it feeds too quickly.
