Speed & torque. I want to be able to cruise along at 60/65 and tackle hills without any real issue - this is the whole point of this. Reliability, I want something I can set of on a journey and trust it will get me there and back. I am not overly concerned about economy.
After that, of course it is budget. I want the simplest, which often equals most cost effective, upgrade path. I also want bang, or let’s say horse power for the buck. There is no point spending X to get Y, when spending a little bit more than X gets me 2xY.
Does that make sense?
