Couldn't agree more about the empty weight of some of these so-called 'carry-on' bags. Mrs TOO bought herself one of these, complete with telescopic handle & wheels. Far too heavy in my opinion. I'm always nearly tripping over the blasted things in the Terminal building (another good reason for keeping out of the place).
Personally, I use a lightweight 'stuff' bag that'll fit in the overhead. If it's a nightstop 1 or 2 nights it's entirely adequate.
Re charter weights - I think the Summer Med flights are probably pretty near the mark. It's the ski traffic that's problematic but depending on a/c type, they bulk out before they max out on weight (mass!). Longhaul is another matter - usually more freight involved, too.
I see Monarch are doing the odd Accra...
Cheers,
TOO
