RE: What "truly" is the advantage (Mech vs. Fixed)
I have been using Spitfires for the last couple of years and I've been very impressed w/ their quality and performance. I have used the same head to kill 5 deer and have yet to break or damage a blade. The heads disassemble easily for cleaning and resharpening. 4 out of 5 killswere passthroughs; one hit the inside of the opposite shoulder. I must admit, they don't passthrough w/ a lot of zip. But I guess thats irrelavent considering my freezer is full.
Although, you guys have sold me on Slicktricks. I'm gonna give em a try this year.
