Thanks guys. To be honest I put
sw+motech+drybag - Google Search
on rear seat and it was just touching paneers from time to time so I was really surprised how it end up. It got a tent, sleeping bag and sleeping mat in it so it wasn't more than 8kg for the whole bag. And I was looking at those paneers and tried to be very gentle with them since it was the first trip since I have bought them. I have givi top case that went through a lot and looks much better than those shad cases.
