I'm building-up '04 S-Works Enduro and wondering if I should use a 6" or an 8" disc on front (I have both size rotors). I weigh 130lbs and do aggressive trail riding. I like the stopping power of the 8", but also like the lighter weight of the 6". I'll be using a 6" rotor in the rear if that makes any difference. Thanks for any thoughts.

You can use 8" if you have 20mm dropout on your fork, otherwise you have chances of your fork not holding up to braking forces that are generated by 8" rotor. You're light and 6" should provide plenty of stopping power for you (I'm 130 myself). If you need more power try going to metallic pads.

Thanks Lucky!

I'll be putting the discs on an '05 Fox TALAS RLC fork. Do they have 20mm dropouts?

No, you have standart qr. If you put 8" on standard axel like you have and if it breaks, your warranty will not save you.
