Virtually same, only sorted and marked by bar size; don't carry 16" picco, nor any .325. so that simlifies things somewhat by eliminating confusion. i like baby ziplox (3 x 6's) for the chains and misc., have all Stihls. Having all one manufacturer and non intersecting chain lengths, limits confusion while allowing maximum flexibility with less pieces that ya have to cover yourself on per 'emergency'.
i keep'em in an ammo box (approx. 6x6x12) enogh room for: spark plug and fuel filter in hollow/ capped file handles, files, 6pack Stihl 2.5g 2/cycle earl, 3/8nutdriver for local fone boxes
also extra of: scwrench, carb screwdriver, cleaning brush for gas/ oil refilling etc., T-27 for Stihl screwheads, linoleum knife w/point for cleaning bar rail/bar's oil port (used anytime mating between bar and saw is diturbed), popular oil/gas plugs and recoil rotor/pulley for my Stihls, lil-baggie of pull cord and drive sprockets, inside that an evidence bag of :Stihl screws, recoil pawls and hairpins.
And then the chains! Though we try to keep the biggest chains out of the ammo box, and with their bars mostly to save space, but usually keep 1 just in case. That kit there has taken us far through many a challenge, and temptation to just get by. Sometimes, just as in rigging, to get things to go write at more severe tests you have to command and also allow them to.
We only try to freshen up chains, allowing a friendly proffessional to clean, lube, set depths, and sharpen chains beyond manufacturer or anyone i've seen. Diffrent long term local-pros may dial-in diffrent angles to higher tolerances sometimes. From there they get put into marked, baggies. Anytime u are down to 2 of anything we try to take note, then 1, then out; that gives 3 chances to keep stuff stocked.
The ammo boxes have proved very sturdy, flexible, compact, fairly dry storage componets that neatly sit in a line, try to paint em diffrent and also can't lose me colors. Have one for jumpercables, Large pulley blox, 5x1 jig and ..........a double tall that nicely fits 200' throwline w/2 balls that we clove hitch the line with top ball to a SherrIll Big Shot's 'yoke' that we then lay fork of down into the ammo box on top of the throw line(s)very nicely. We always have a ball on each end and between lines. We also used a double tall for original Porta Wrap and slings. Hard to go wrong with Ammo boxes, esp. if ya bargain hunt.
