Great minds and all that, I'm always tweaking what I carry with me, I don't have room for surplus items, decent multi purpose items are ideal, I don't carry sockets or 'sets' of anything, just relevant sizes that fit something on my bike.
The main criteria is, it must fit in the toolbox, or stow out of the way, I have a lithium battery that is shorter than the norm, so a couple of spares can be stowed on top of that. Personally, I really dislike the leather tool rolls hanging off the bike anywhere.
Of course, the best bit of kit is the recovery card in my wallet.
