Lines - nerdy question

So, I've noticed line manufacturers seem to like to keep a 4g weight difference between all their shooting heads? Looking at rio and gaelforce for example, the head weights go up from 30, 34, 38/39, 42. Loop 31, 36, 40.

Only Airflo (with the rage compacts at least) seem to go up in 2g intervals.

Considering rio seems to like making about 5 variations of every single line, why not make smaller intervals? Yeah sure, a rod's casting window will definitely fall within one of those lines, but what happens if you like a slightly more/less load and the next line up/down in their manufacturer's range it too big a step?

Having a line a few grams lighter or heavier than the rod’s recommended casting window will not make much difference. I regularly use 44 gram shooting heads on a rod with a 41 gram recommended line weight. I sometimes take the wrong weight heads to the river for the rod I have, so end up on the river with a 14 ft rod rated 9 weight, but only have a selection of 8 weight shooting heads. Half the time I don’t even notice.

Should you want to be very technical, you could buy shooting heads that are designed to be cut back at the reel end to be a specific weight for your rod, such as guideline triple Ds.

2 grams is too small to notice for 99% of anglers.

Lines made for the US market are weighed in grains and generally go up in steps of 50 grains, which equates to 3 grams.

The majority of salmon fly lines are made by a small range of manufacturers and rebranded and packaged by companies like Loop, Guideline, Vision, Gaelforce etc.

Weight is NOT the only issue !
The length of the head AND the taper (even distribution of the weight or more weight to the back?) will have a huge impact....
Much more than many think !!

Cheers folks was a bit of a thought just because I noticed it with the single hand, and wondered if it extended up to the 2 hand.

that would be an extension, say if you enjoy the taper of like the Rio AFS, but wanted it in 36 g. But I definitely bow to MCX's experience on this as it was completely a thought on my part.

And ofcourse MCXFisher is 100% correct in what he writes.
I just put the other dimension into the picture.
Normally I make jokes with friends in Denmark who tells me that a certain rod only will cast well with (let's say) 31,5 gram and nothing else....then I say - okay - we make a head of 3 metres then.... :)

Oh certainly, like I have a 15ft Loop Multi that I used all spring and felt a deeper load/better response with a 40g Loop GDC head than I did with the 42g Rio AFS. Which also semi inspired my original question, as I would wonder what a 42g Loop GDC head would be like and if it would be noticeable at all 😅
