Fork oil weight for Kayabas

I have a 2003 SV with a Kayaba front end from a 2003 GSXR10000. I recently had the
forks serviced, and am starting to notice too much damping over washboards bumps,
sharps bumps, etc. According to the shop, they put in a 'heavier' weight fork oil, on
the order of ~15wt. I see that RaceTech recommends around 5wt when mounted on a GSXR.

Does anyone have recommendations for viscosity/brand for this setup? I'm around
