I had TechSpec on my ZX14, and now I have it on my Concours 14.
I didn't like the middle tank part (where your belt is) so I cut a spare tank pad and put it up against the provided pad, above it, between it and the filler cap. Now I don't have to worry about my belt.
I prefer the SnakeSkin, it is the thickest material they sell, and looks really good.
I just now got a set for the tops of my side cases, since we tend to marr the tops getting on and off.
TechSpec even made me a custom pad for my ZX14. I sent them a tracing and they made it to order, for not much more than the cost of a stock tank pad.
There isn't anything better than TechSpec. It looks good, will stop a big belt buckle from marring the tank, and it lasts forever.
Even the Geelong protector, as sexy as it is, will abrade and eventually (in a year or two) delaminate and need to be replaced.
