Cartridge retip stylus options/Opinions please

Hi guys,

I have two cartridges that I want to have retipped: Shelter 901 and Monster AG2000. The Shelter comes stock with an elliptical stylus and the Monster with micro ridge. Andy @ Needle Clinic will put a microridge on either for $450 ea. (line contact for $350, elliptical for $250). Soundsmith will put their best stylus (optimized nude contact line) on a sapphire cantilever for $399 ea. Both carts (esp the Monster) is very good in stock form based on my tastes; but, if I had a magic wand, I would say that I would prefer a little more openness and refinement in the highs with somewhat less emphasis on the mid bass from the Shelter; and a little more fullness from the Monster.

Any thoughts on the general quality of work to be expected from each retipper and/or the merits of each choice of stylus would be most appreciated.

Thanks!
