I have the ones that are a step DOWN from the Lux grips that you guys have pictured. I heard better reviews from mine and they are cheaper and look better IMO. PJ's parts all the way. Great to deal with and fast shipping.
Mine have definitely made street riding and cruising on the highway a bit more comfortable. They eliminate a little bit of buzz even without bar-ends. To have them mount flush and even, you do have to remove a little bit off of the end of the clip-on, but not much and nothing you can't do with a hacksaw in about 5 mins.
