The stabilizer configuration I had on my Stingray was a Sims Enhancer 2000 with a vibracheck isolator and a screw on enhancer to boot. I don't feel like I was getting much hand shock at all with this setup. Ditto what davidmil said about PSE's NV system. I considered adding it several times but just never did.

I used cat whiskers on the string & they worked OK. You may want to try string leaches. Lots of folks swear by them.

Hope this helps.
