New boy says 'which Monster' ????

Hi all

I am new to this forum but not new to Italian bikes.
Having owned 97 900ss, 95 M900, 03 Multistrada.
A few other V twins including a Tuono, a TL and just to be different
a Cagiva Navigator (fantastic bike by the way)
Anyway I now find myself in the market for another Ducati and I am looking
for your opinions.
My short list is all air cooled......S2r 1000, M1100, M1100s or 1100evo.
All have pros and cons but I'm interested to hear your opinions and experiences.
Cheers.
