[VFB] Thread FYI

[DMurphy832]

Got this info from Henk Verhaar, an excellent tyer:   "First of all, there is no real logic in the 'ought' scale other than that 6/0 by one producer is (or should be) thicker than that same producers 8/0. Denier is actually also an obsolete measure, superceded by 'tex'. Denier is grams per 9000 m. Tex is gram per 1000 m. A 100 denier thread weighs 100 g per 9000 m, or 11 g per 1000 m. At that weight, it would be 11 tex or 110 dtex. In practice, denier and dtex are used as virtual synonyms.... A thread that is twice as heavy per length as a structurally similar other thread is not twice as thick but sqrt(2), or 1.41 times as thick, since weight is proportional to volume, and with equal length with diameter. But again 8 / 1.41 is not 6, so there still is no real logic in the 'ought' numbers. UNI's 17/0 is 40 denier...."   Now my "go to" thread is 14/0 Griffith's Sheer (available at Line's End) which Fred Reese (fishing buddy of George Harvey) turned me on to some years back while demonstrating some exceptional spinner patterns made with what Byard labels "sparkle organza" under the "body parts" section at Linesend.com.  It's just strong as any 8/0 I've used and stronger than Danvile 6/0 but with a finer diameter.  I use it on all flys under #14 and some up to #10.  For flys requiring you to split the thread, the UNI 70 Denier should work fine for small stuff and the 140 Denier for larger flys by my estimations.  Both will do fine when incorporating the magic tool in my opinion.   Murf
