Gnarshead, I strongly suggest the CRG hindsight stuff. I may have gotten them at MC superstore, or one of the people who provides goodies for our types of bikes. they are more expensive than the other options, but the best rated, and I had no vibration problems. Will post some pics tomorrow. You will also have to get the Rhino bar ends, but do not have to remove any of the existing weights. The downside is that they are not as big as the regular mirrors, and you have to look down a little versus looking ahead and just moving you eyes slightly with the regular mirrors.
I also have put on the extenders for my regular mirrors, but unless you locktite them after you get them positioned just perfectly, you can end up getting some unwanted movement. I hear great things about the Aprillas, and they are not very expensive. the ones I have fold in on a pivot, and will kick in it hit. Have not dropped it with them on, but imagine they would not survive well. I have both an oval pair and a teardrop pair, and may be willing to part with one. Let me test them over the weekend.
