I am with you on the "all rounder" approach.
The need for that kind of thinking would cause most tuners throw up their hands and start talking smack.
My ride weight can easily vary by 120 lbs with travel gear and gas.
I shudder to think of ever adding a passenger plus gear.
Keep testing and thanks.
