Thanks guys for all the info.
I apologize for not including all the options, as I told VC3 yesterday, perhaps I wasn't the best person to start this poll but I thought it might clear up some of the confusion on what seems to be the biggest "Achilles heel" of these bikes and help mbrs make an informed decision wrt replacing it.
I tried to modify the poll, however, I cannot without completely redoing the thread and poll then getting the mods to delete the old one, thereby loosing data. Perhaps, like you say, the mods could edit the poll to include the other options presented here?
