I have an old Streamlight Excalibre 5D with 6C NimH in it. This would be much like your 6C. It runs a WA01111, as it's the correct number of batteries and the 1111 doesn't have a great beam in any other light I've tried.
For jollies, I ran the ROP HI in it, and it is every bit as bright (and maybe brighter - no way for me to go head-to-head). As a bonus, the ROP HI has a pleasing beam even in a SMO reflector. A LOP reflector is just icing on the cake!
I would very much recommend the ROP bulbs. I believe there is even a set for Alk batteries, though I know not how bright it would be.
