Solo'd this today, 75RDM/37NIN... Not that hard if you remember to keep Slow II and Paralyze II on it, and use Stoneskin religiously. The problem is that it is a long fight and most people get impatient. Dia III was extremely helpful. If Stoneskin and Shadows wore and I was unable to get them back up, I used Bind and moved away.
EDIT:
Just solo'd it on NIN75/DNC35... As long as you keep Hojo and Jubaku on it, and use a Stun Kukuri, you're good. I'd also suggest using Demon Arrows. I used an Accuracy/Strength setup and two Super Potions.
