If you managed to bend your stockers then Excels are a great option.
I have a stock front and a rear excel on my bike. My back rim was fine, but I caught a VERY good deal on it. ($37 brand new) I couldnt pass it up. But anyway, its a little bit lighter than stock, not much at all, but noticeable rim to rim. It is quite a bit stronger than stock, but I havent really smashed either one of my rims. My only complaint is, the color scratches easily (mines red) and you have to be carefull with the tire irons. I ride a little bit of gravel and rocky stuff, and havent scratched it yet. So I think it holds up very good.
I did hit a little gully once at about 40mph wheelied over it and didnt realize how big it was. It was between 2-3 ft wide and 3 feet deep. My back end took a huge jolt, my shock soaked it up fairly well though. Didnt bend my excel.:)
