Thanks for all the replies, I guess it may be time to explain the post.
I already had a '14 plate Gs in the garage, with shift assist pro etc etc, but couldn't get away from hankering after an 1150GS, Anyway, one popped up for sale in the Blue and White striped colour that I like, so I went to have a look at it. Fastidiously cared for, with Touratech luggage, HID lights, Tank cover etc etc but otherwise standard, I eventually gave in to temptation and bought it !!
I've not had it long enough to know for sure, though have put over 1000 miles on it in 10 days, I'm rather liking it.
So for now, I have both, but in the future, if I had to get rid of one, I have suspicion already which one it will be !!
Hopefully I'll be down at the Devon weekend on the 1150, see you there !!
P.S. Thanks to John the previous owner for looking after it so well in the past, I hope he enjoys his new bike ......
