I like the bigger body... When u use bigger lenses such as a Canon 50f1.2 or a Konica RF 21/35, it balances nicely.
I have never like the heavier m or ltm lenses on my Ricoh gxr mainly due to this now being lenses heavy... But that is just me
If the guys at the store will let u, bring an sd card with u and take some shots with the 35.. Maybe u will walk out with a new camera.
But honestly, photokina is around the corner in September, might as well c what is announced by everyone.
