I have had them(MeanV's)on both my 07 Commander and more importantly to this thread, my 08 101st. They make big difference IMO. On the 101st I ordered a Mean V to match as soon as I ordered the bow. I just took the factory off. Would it be cool to order a new roller that didn't have the hole in the end, maybe, but it wouldn't be the end of the world. Order a Mean V and roll with it like that.
Here is the Commander in the MO Brush.
The 101 in MO Max 4.
