Hey David, how's your optical sensor working? After a bit of trial and error with mounting the foil (I think the foil has the same coating as Bill Clinton...almost nothing sticks to it!) we have the two originals and two more in Shreveport, they all work great! The one I like most is the Futura SE whith the .80...OMG, I LUV this thing...now if I can get the SE with the .60 to smoke I can get another .80 (like I can find another 24 tooth clutch bell...) Chris
