Default Re: Reels to balance a rod?

Quote:
I will give you this in that the rod does store energy and releases it to the fly line but once the line is moving it's simple momentum that carries things along moderated by the drag of the air, wind, wobble, your tight loop or not, etc
That is how I view it as a layman without a college education. Not all of the kinetic energy developed though our bodies winds up in the rod, nor does all that which is in the rod transfer to the line. Therefore, line momentum is the final result of KE after the cast has been completed.

If it was momentum we could not shoot line because adding mass would have to decrease velocity linearly to keep the momentum constant after the haul.
The fly leg velocity does indeed decrease when we shoot line and increases again after we clamp it due to Newton's 2nd law , the conservation of momentum, and is why bull whips are tapered. As mass decreases, velocity increases.

Drag does indeed increase as the square of it's velocity, which means that the faster the loop speed the greater the drag. Since drag, on a non shooting line acts primarily on the loop face, the surface area of that loop face for practical purposes is what slows the line the most.

That is another reason for not trying to shoot line into a head wind. You shoot line with the wind into the backcast and shoot nothing into it. Otherwise, you are just pissing into the wind.

Since surface area is strictly a multiplication formula, whereas volume (and consequently mass) is a squared function of radius, the drag is not increased that much between a 6 wt line and an 8 wt line - not nearly so much as the differences in mass. Therefore, 8 wt lines carry better into the wind than 6 wt lines.

So as not to bore everyone, Chuck and I are discussing by PM.
That's too bad. Give us a final synopsis please, 25 words or more.
