Nearly swapped my 100LT in for and 11RS many years ago as at the time I thought I was bored of it - many bikes later I realise I was mistaking boredom for abject capability.
My buying decision now is basically: I need a 6K service interval if possible - easy to work on, well put together and comfortable. It also has to handle 30K miles per year commuting then another 10K for fun! - to be fair there probably isn't anything else that ticks the boxes like a K series Beemer.
(I'm also starting to do a bit more work at cycling events and looking to join NEG next year so need something that will run at 30mph average for 10 hours a day then a 2 hour ride home at normal speeds) again - I can't see anything else other than a K doing it - either an LT or an RT dependent on engine size!
