i think the world of Roger. he's articulate, colorful, accurate, shares his world class knowledge with us little people, has a good looking wife, consistently questions the status quo, and because he is not a "pole guy" it's exactly a waste of his very limited time as the fellow for a correct review of trekking poles.
i read every post Roger tosses at us (as well as Doug's), but for the life of me can not fathom why he got tasked with reviewing gear that to a large extent, he does not use or particularly care for.
there's stiffness, strength, compression limits, grips, angles of grips, weight, swing weight (which is more important), inertia, and the list goes on and on for developing the "perfect" pole.
did i mention Roger knows eff'n Every-Thing about tents.
fabric. poles. sewing. bonding. designing. caternary compensation. wind loads. snow loads. ventilation. etc.
most of us occasionally Buy a tent. but Roger Builds his tents. and he apparently does this fairly often.
then he takes his cute wife and cheery-bob off they go into a nearby storm. after which he comes back down for crumpets and writes a review on thread.
and fabric. Roger's is the go-to fabric guru.
thread ? no worries. whatever thread you're currently using is valueLESS. ALL thread ( ...almost) is unworthy of being sent thru a needle.
the only correct thread for a tent is (i forgot, but it's a mofo to buy in the states). Roger has measured (repeatedly) the strength and abrasion resistance of any possible thread you can find, and they all pale in comparison to the "correct" stuff. even then, if you could find this mythical filament, you'd stupidly buy the wrong type/weight/denier/compound/ .. it would just be wrong. and that's Ok, you'll live thru it (at least i did), you just won't be doing things as well as is humanly possible on the bleeding edge of what is attainable ... if you dedicated your entire being to it.
i'm a huge fan of R's. his review is a management error. it's just a small one. and bpl will survive.
