Geez Taz I wasn't aware of your health problems (to that degree anyway).
I admire your will.
I'm questioning your reasoning though..... The decision to ride again under these circumstances is sketchy.
People drive like sh!t dude! The last motorcycle wreck I had could not have been avoided. A young girl (17) pulled out of a parking lot directly in front of me. I was going straight and she made a left hand turn that intersected my path........ there was absolutely no where to go....... all the options available were bad. One second to decide. I still think I made the right decision (best option available) and got lucky.
Recovery took a long time (broken arm, disks in my back, numerous cuts and road rash), and I considered myself to be in excellent health.
I was not wearing all black.
The power to weight argument seems to make sense for you (although two up is out)........ but when you are faced with no options........ the price you might pay could be higher than another in the same situation.
Build the drag car........ literally it's safer!
* EDIT
My last wreck happened after just coming back from a 5 thousand mile motorcycle trip that lasted two weeks........ I had been home for a couple days, went down to the gas station (around the corner from my house) to fill the tank.
