Long fiber wool is the best for internal damping followed by fiberglass with everything else a distant third. Altering the quantity and density of damping material will alter tonal balance and attack characteristics. Increased quantity / density will enhance low frequency extension with a decrease in mid-bass output while a reduction will increase mid-bass output at the expense of low frequency extension. One can fine-tune the quantity to adjust for room acoustics and / or personal tastes.
As far as using modeling clay, i would be afraid of vibrating it off of the baskets over time. Sounds like a "quick & dirty" approach that may be worth checking out though. After all, if you've gotten ten years out of the clay with nary a problem, it sounds like it could offer the best of both worlds i.e. extreme mass with complete reversibility with minimal mess during application.
Capaudio: Reliable sources tell me that Audience Auricaps have been bettered by Moncrieff's latest caps, the "TRT Dynamicap's". The Audience caps are supposedly VERY good though.
For those interested in such things, a phenomenally well put together source for finding specific types / brands of caps was put together and can be found here on the
Faradnet website that is free of charge. One can look up caps by dielectric material, manufacturer, etc... Very handy website if looking for "tweaky" caps, etc... Sean
