Re: Pull the line first.

Synchronizing peak haul velocity with peak rotation velocity is counterproductive. It must take place later to give the best results.

Re: Torque Twist

Good points Graeme, I agree with your analysis. For sure it would be ideal to force the unloading in the direction of the cast, which might not be that easy. I looked at the video with the HT6 and there is still some PB as you twist the rod handle. TTe.JPG Nice loop indeed. My attempts to significan...

Re: Torque Twist

Thanks for these very interesting videos Graeme. The rod is slightly unstable, which is rather normal for a glass rod. It must be on the low side of speed by comparison to a graphite one. The rod can vibrate on his first and second modes (clamped free), and this is emphasized by PB. I wonder if you ...

Re: Torque Twist

There are many ways to make harmonics pop up, but it occurs as the rod is stopped, or eventually pulled back. In that case there is a physical constrain on the butt of the rod magnifying the S shape since tip is moving forward on its momentum and butt is moving backwards. That can happen without pul...

Re: Torque Twist

Hi Paul Your last sentence lighted a bulb somewhere, and I gave another look at the video. I can identify a pull back coming from your forearm. My best guess is that you twist your wrist at the same time you PB. The S shape comes from the PB, just like for a snap cast, the rise of the rod butt moves...

Re: Torque Twist

Ok so let's consider that the spine of the rod does not interfere. There might be a possibility related to biomechanics. We need the help of someone knowledgeable in that field. Could there be an induced deceleration coming from the TT? Such phenomenon (induced acceleration or deceleration) is menti...

Re: Torque Twist

Hi Sakke My guess is that you are assuming that some bonus coming from the TT is linked to the spine of the rod. The extra stiffness of the spine may result in extra tip speed (stiffer means faster). Let’s assume this is true, a possible consequence is the following: since some rods can be spine les...

Re: Torque Twist

Hi Paul So in fact you get a higher speed because you change your input for a quicker stroke on a shorter arc. That is the main source of extra speed. I let aside a potential small benefit from another harmonic (S shape), and I concentrate of the inertial effect which can benefit to a sharper stroke...
