I don't have a FSH. I did a 6" comparo back in 2007, I think. I compared the S6, M6, and ASH1 SE in chopping, slashing palmettos, and overall cutting. The S6 came out on top as best overall, the M6 was the best chopper, and the ASH1 SE was the best at palmetto slashing or machete work. Since then I got a Skinny ASH1 and convexed it. I liked it so much, I sold off my old beater S6 after enjoying it for two years.
