Mono has memory and if you are shooting to the stretched end of the line those kinks in the line are going to cause a lot of drag coming tight. Your end of range power is going to be less than if you have loose line, that doesn't pull back on the shaft.
That seems like a fair point I recall telling you about a shot I missed on a big yellowtail with my Albacore 130 and one wrap a couple years ago. I was just sure the fish was within range of one wrap, but the shaft seemed to veer off. 400 pound mono does have a lot of memory, so straightening out those kinks has to rob some velocity. Presently I'm using the 1.7 mm stiff spectra so that shouldn't be a problem, but I'm still afraid to use one wrap.
Since the green water is keeping me from going diving, I've measuring and over thinking this stuff. Here are some ranges for my guns with single wrap:
Denton 120- 16.5 feet from the muzzle, 21 feet from the handle.
Denton 110, 14.5 feet from the muzzle, 19.5 feet from the handle.
For double wrap add about 9 feet for the 120 and 8 feet for the 110
Is it fair to measure the range from the handle rather than the muzzle? I would think so. The length of the gun is part of the distance from my eye to the fish. Of course my measurements are just to the range for the tip with no penetration, but surely my arm will be extended enough to allow enough for that.
So Castranova, I know you have a lot of experience with the 120. Do I really need more than a single wrap and 21 feet? Can I really get penetration farther than that? Two wraps is way too much. If I need more, I may put a half wrap line guide on.
My range for my Ulusub 155 (61") with a half wrap is 23 feet.
