Thanks guys.

I'll perhaps have a look at figuring out the sag sometime, but I've read through stuff on suspension many times and it all goes over my head. I'm really looking for something like "I am a scrawny guy and I have my preload on 1" and "I am a fat git and so's my wife, and I have my preload on 4". Nice and simple.

I won't look at it for a week as I'm heading off for a tour of the Scottish Highlands and islands tomorrow for 8 days. Luckily my spine will get a nice rest, as I'll be on my K1300S with ESA, so I can just push the button for "fatty with luggage" and off I go!
