When it comes to multi-tools, I admit, I carry a Leatherman. I have two Super Tools, the Micra(Recently misplaced), Original Leatherman, and PST II.
I recently handled the SpyderRench and, although I loved the design, I don't see it as a replacement for my Leatherman(s). IMHO, it seems too "unlike" a Leatherman. This may sound strange, but the overall design of current multi-tools, like the Gerber, Leatherman, or similar, seems to work best. You know, the "folding pliers" design.
I've seen posts where the SpyderRench "fell apart" while using it. Not just one or two posts, but a number of them. I don't know, maybe it's just me but the SpyderRench seems too complicated. Then again, I find programming the VCR complicated! <img src="smile.gif" width=15 height=15 align=middle>
Just my thoughts. I AM a hardcore Spydie fan, just not a SpyderRench fan...yet.
Kahz, I think "el hombre" will really appreciate all of the research, thought and effort you are putting into making this decision. I wish you well. <img src="smile.gif" width=15 height=15 align=middle>
