Hey guys and gals,

I finally was able to see the 816 hybrids yesterday in person and they really good (a little over an hour away from where live). But they did not have the 915 hybrids to compare them to side by side. I'm having trouble finding the actual size of both the 915 and 816 hybrid heads.

Does anyone know the cc's of these hybrids, 915H/HD and 816H1/H2?

Thanks so much for your help!
