Wow! Thank you so much for all info! I guess type of leather is important factor then.
I found k35 Togo a bit heavy for me, and k28 (clemence) ok. That's why I've been worrying about weight of B30, as it could only be handheld.
I find myself 'defenseless' seeing k or b or c in H shop, so I better make up my mind and gather more information before making request to my SA.[emoji5]️
