I have the Bellacorse Western bars on my T100, after trying the M bars. The M bars were beautiful, but for my 5'7" height, the reach was uncomfortable. The Western bars are similar to the stock bars, but much more flowing, and for me, quite comfortable. I have a pair of NOS Beston Gran Turismo grips on, and am extremely satisfied with them. The only source I have been able to find for these, in the 1" diameter, is an ebay dealer:

This dealer has been quite good as far as price ($9.95--cheap for these) and they seem to often list them. You need the 5.25" grips for 1" bars (1 and 1/8 on the throttle side). Note that it is difficult, though not impossible, to mount these with bar end mirrors. Aside from the shape, which is quite comfortable, they are grippy, so I find that I can ride for hours with the wrist cramp that plagued me after an hour with the stock grips. Bellacorse also sells "football grips" that are similar.
Bear in mind that what works for one rider may be wrong for another. Since many of us on this forum are less limber than when we first started riding, issues like grips and bars, and seat modifications, become pretty important.
