I am always so fascinated by these discussions hahaha
All I can say, as I have so many times, is that barrel length is meaningless and all that really matters is barrel weight and how that weight is distributed and that you personally like that feel.
Barrels longer than 75cm have not attraction to me as they are usually heavier than I care for. Well, that and I don't have a gun case that will take longer barrels. I do know that longer barrels are easy to sell since I've never had a problem flipping those I've tried. And I notice that there are always lotsa long barrels for sale so that may say something about them too.
Anyway, your $, your choice
