Thinner Lines = higher speed

[VGB]

Me also, what is the end game? I often fish a #4 zxl on the chalkstreams but carry 2 lines, a #4 GT90 for dries and a #3 small stream for nymphs. The leader set ups are different. Last night, I fished a Steffen #3 Glass to throw #12 mayfly patterns with a #2 Supafine line, I make these changes depending upon the required presentation for certain conditions up to a certain distance. In making these decisions it’s the fly, leader and line taper that drives my selection, AFFTA weight is a secondary consideration. I haven’t weighed it but I wouldn’t be surprised if the first 25ft of my #3 smallstream set up weighed more than my #4 GT90 set up, excluding the fly but including the leader.

I was assuming that it was for different lines on a single rod. Your answer puzzles me

With the single rod I think that the answer is obvious. It’s that the cycle is faster with lighter *outfits* where I was looking for the answer. Let’s say take the same ERN numbers throughout the range. Why the difference?

Just played with a single set up and my casting cycle at the fast end is limited by having to wait for the loop to unfurl before starting the next half of the cycle. However, I can have a range of cycle rates with fairly similar loops up to that point.

I can see that before we can get to the “why” we have to get to the “if” Do you find that with a false casting cycle that a lighter line class is faster/slower/same as a heavier outfit?

The situation depends on the design of the rods, and ERN has little to do with it, IMHO.

When I return to my boat I will hand-cast the respective lines to remove the rod from the equation. Which is in essense what I’m discussing

Another interesting experiment would be to throw multiple line weights on a very stiff rod simultaneously...

Sorry I’m on my phone Lasse. Did the lines unroll at the same speed?
