clubman bars are simpler and cheaper and get you about the same riding position. The down side is that they aren't as adjustable as the clipons. If you go clip ons, then you'll likely want to modify your upper triple clamp to get rid of the handlebar clamps. Also, if you use one of the aftermarket fork ear sets, they are angled so that you can mount them one way or the other to get your headlight positioned right where you want it.
Try the clubmans first and make sure that you like the riding position. Then go for clipons and mod everything to make for a clean install.
