It looks like youve narrowed it down to the Buell or Monster. They're both great. In my area both the Ducati and Buell dealers let you take test rides. Test ride em and buy the one that feels best. If your dealers wont let you ride, at least sit on em and see how they feel. If you still cant make a decision(i.e.:" I want both!!"),go to the dealers with a stop watch . Look at the bikes; buy the one that gives you a woody quickest. In other words,buy the bike YOU like best...dont listen to us opinionated jerks! Now... if you ask my opinion as a 50 something guy, I think the 800cc monster will meet your needs and your rusty skills perfectly.
