I'm not a smith, but I've used my share of extractors, and Wilson Bulletproof has been my choice for a few years now. Once properly tuned, it holds its tension longer than any other I've tried, and doesn't seem to wear/break as quickly.
Also, do a a search under "extractors". There is a lot of info on them there already
