the big rod making companies don' t even bother with spine, they just put the guides on randomly- and you never hear people complaining...
In other words they' re knowingly making an inferior product to what they could be making with a little more time. But, by making the inferior product you can get more production. You never hear anyone complaining because most people don' t have the skill to tell the difference and the ones that do have the skill and use the product are generally paid to promote that line of rods. That about got the situation covered?
There are quite a few guys here that do have the necessary shooting skill to see huge differences in arrows that most people would never notice.
And I think maybe I' m seeing what you' re saying. You' re talking about shift in spine orientation while the rest of us are talking about degradation in relative stiffness.
