Handlebar setups?

[zuren]

I'm finally shifting my stable around and have added a Surly Ogre frame that will be built up with parts from another rig and as money/time allow.  I was looking forward to trying a Jones Loop Bar on this rig but it appears that Jones no longer makes a 25.4mm clamp diameter variant.  The stem I have is a Thomson Elite 25.4mm in like-new condition so it is hard to justify ditching it just to go to a 31.8mm clamp diameter.

I'm curious what others are finding to work well for attaching lights and other accessories?  Are flat bars better than risers?  I have a couple riser bars but in most cases, you lose the real estate at the bends for attaching anything.

Or should I just suck it up and drop the coin on a new stem and go with a Jones?

Thanks!

I have 720mm lightweight flats with slight backward sweep for like $25. Lots of room, but much of it is taken up by aerobars and on-the-bar thumb shifters. I put the light on the aerobars.
