Weight of B30

My new b30s are very light. Especially the new togo which is thinner than my older bags. I don't currently have a kelly but used to own a k35 and my b30 is much lighter and easier to use.
 
I have a B30 in Togo and I've never felt it to be too heavy, even when it's very full. I've held the 35 and find that to be much heavier, even if it's almost empty.
 
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]️
