I've used the Kinman Avn Blues set for almost a year now and I love them! I use them for recording and they are 100% quiet. My reasons for buying them were
1. Authentic wonderful Strat sound without ANY hum - none whatsoever, even standing 2 feet in front of my computer screen.
2. Better balanced string-to-string than any stock Fender pup.
3. Awesome service and advice. They come with easy-to-follow instructions on replacing them yourself (which I did). Just check out Chris Kinman's website
http://www.kinman.com/ and you'll see that this man is a Strat afficionado.
The Avn Blues set is a little hotter than stock Strat, but cover most genres like Rock, Jazz and Pop (not just Blues!) I understand the Woodstock set is more vintage sounding, maybe like a late 60's Hendrix-y kind of clean sound. There are great descriptions on the website, in case you haven't looked yet.
Before the Kinmans I tried Seymour Duncan Classic Stack (noiseless) pickups, but although they were a vast improvement in the hum department, they fell short in tone (same as the DiMarzio Virtual Vintage from what I hear). Lace Sensors didn't fare much better.
If money's no issue, the only other pickups I would consider if concerned about retaining an authentic Strat tone are Lindy Fralin (you'd have to find out if they're totally noiseless though, as I don't know).
