Tom Kirkman ( da, iar):
A word about spine orientation and casting - in controlled mechanical casting tests we never found that spine orientation made any difference in casting accuracy. The lure goes in the direction the rod tip is moving in at the moment of release. Even if your shaft (blank) was twisting around its own central axis, that plane will not change. We used 0, 90 and 180 degree spine positions and other than some changes in distance due to the particular power of the blank in any given plane or axis matched to the particular casting weight, no difference in accuracy was recorded.
What we did find, however, was that blanks that were badly out of straight, i.e., which had extreme curvature or warp, could cause a great deal of accuracy problems if that curve or warp was placed far from the casting plane. This is another reason for building on the straightest axis, that is, if you want the best accuracy possible.
In either case, you do have to remember that in certain types of fishing it would be hard to make all your casts in a particular and perfect plane.
(practic toate informatiile le-am obtinut de pe acest topic si de pe cateva site-uri de specialitate) si, prin urmare, imi cer scuze dinainte daca voi gafa cu afirmatia de mai jos referitoare la spine.
