I have had an XL for about 5 years, like most things is not perfect! Mine has about 50 hand tools in it, plus accessories like spare blades thus is heavy.
The zips can be annoying, but it carries well with the strap. Hammers/pry bars no problem. The tallness makes it awkward to pack in car boots. LC or open top version might be worth a look.
What is an S2 Midi or an attic?
