If you ask someone to open several boxes of SA UST shooting heads you might get exact weight what you are after. This text is copied from SA pages:
"Have you seen that little sticker attached to the UST line when you open the box..? I often get questions about this sticker...here is an explanation. On one side of the sticker you will find Line Weight. Under line weight you will find a handwritten number. The line to the right in the picture, you see handwritten 524gr. In the USA they use the measurement Grains instead of Grams. 524 Grains = 33,95 Grams. This means that EVERY SINGLE UST LINE has been weighted by hand before it leaves the SA factory. This is quality assurance/ quality control.
I have handled many in the recent years from GL, NextCast, Airflo or Rio, and have yet to find one which weights more/less then 0.3 gram.
If would be nice if SA UST were 7/8, 8, 8/9, 9 etc. instead in 60 gr or so increments. They claim UST are better b/c no need to adjust from the back ( like GL 3D).
If they made in 30 gr or so increments the marketing argument could hold, but with 60 gr........:Eyecrazy::Eyecrazy:
We all know that most of casters/anglers even at mid-level skill will feel 30 gr difference. What if an angler likes rod at 490 gr , UST 460 is to light and 525 a bit to heavy.
Do not get me wrong, quality ofUST line is great, and they are very good heads, if you are lucky that your rod fits perfectly into what they offer.
