As long as you're soliciting opinions consider replacing the petzl, camp lantern and bike light that requires 4AA batts with one 3AAA headlamp that can remain on the helmet. Back before LEDs I toured with one 2AA flashlight that could burn for only 2 hrs before it was dead. My night vision was much better back then but basically I was off the road long before dark and only used the light intermittently. Last one week tour I used the 3AAA helmet headlamp and the batteries lasted all week. I didn't use it more than 15minutes/day. Just something to consider, you can put three spare lithium batteries in a cut off latex glove finger then put them in with the spare tube/tools. I've used that set-up for commutting using it on BRIGHT strobe or med/low constant. On high setting it'll burn out in a few hours but on low and strobe turning off when not needed I've gone a couple weeks without recharging the AAA batteries. One time commuting I forgot my main headlight and only had the 3AAA Eos headlamp to ride 10miles home in the dark. I replaced the rechargables with the 3AAA lithiums and had a useful 1watt headlamp for the ride home at 11pm. Not ideal but adequate.
My impression with area lights is that it takes a LOT of lumens to light up an area and if you need a reading light you're better off with a flood light on low setting a couple feet from the book and a regular LED light pointing into a water bottle makes a fine area light. LED lights with low settings give one the option of stretching battery life a long time by using low output.
bungies, instead of the regular 1/4"-5/16" heavy duty bungie make your own with 3/16" bungie and plastic clips like these :

in the 5/32" hook size. I've been making 2 1/2' bungies with these and they enable one to wrap multiple times around a bag onto the rack. A long 3/16" bungie can securely hold a bag down at four contact points to the rack.
