Those globs were a real challenge for me in the 8" , but it was a goal of mine. Good seeing is VERY rare here in MI... but I'd set my plans. CSC FINALLY gave me a clear sky and I drove 2 hours alone to a dark site I'd picked out. I had charts & notes all printed and went for 3 of the brightest. It took a fair while to get and confirm, but I got G1, G76 & G78!!! That was fall in 2006. Fall 2007 NEVER even came close to skies good enough to try  .... You should have better chances in the 10" for sure 
As for your Ultrablok, its a decent narrowband and should perform much like the OIII....I've had opportunities to compare it to my DGM-NPB and an OIII. Performances were similar and on most nebs the differences were rather subtle to me (I asked David K for some help and went with the NPB - I like it alot, it adds a red band that isnt present in the ultrabolk which helps on some targets)
Good luck & clear skies
Steve
