I have Toshis and I would probably call them the most reliable part of my bike.
Really? More reliable than either of your panasonic frames, or your sugino 75. In that case I will trade you 4 sets of new toshi doubles, 1 for each frame and 1 for each crankset. They are more reliable, just think of how much safer you will be.
Ahhhhhhhhh... the peace of mind just walking around with 5 pairs of toshis on my shoes at all time. Priceless (or for you a trade).
