Well I figured I would post and update on this upgrade I just did in case others are thinking about the same thing. To me it was a no brainer as the surface planer cost me nothing except the aggravation of having to find replacement knives and tear out on figured woods. In the video I'm running some curly maple I got from the Ambassador from his "tour de wood" visit. I don't know if you remember Larry but it had quite a bit of tear out. I replaced all the 2 sided hss cutters with 4 sided carbide cutters. Also in the video I made sure to feed the board into the planer in the same direction as was originally surfaced by looking at the tear out.
