Grain mass Rule?

Got a question for you all. I searched for the answer here on Spey Pages, but no luck.
Was cruising thru Poppy’s Spey Forum and read the following: “Been using them since they first came out (FIST line) i am able to toss 10-15' of t-17 without issue, providing you follow the grain mass rule”. So my question is what is the grain mass rule? Thanks

I’m not sure there is one. Maybe ask him that said it, or was it an old post?

At some point the total weight will become simply too much for the rod to handle, but it is likely that you will find it “not fun” to cast far before then. But before you get anywhere near that that total weight the more important thing is to match the tip to the head. The grains per inch (linear density) should drop going from the end of the head to the tip, but be in the same ballpark. That is what helps with the energy transfer and hence the turnover.

He might have been talking about an old-timey rule you sometime hear people say not to use a tip on a skagit head any more than half the weight of that head. In my experience most of my fishing with even long lengths of t17 (rare) is way below that threshold.

For what’s its worth I still find it “fun” to cast 15’ T17 with a 630-660 head on a 9 wt rod. And I’d say the same amount of t14 on a properly lined 8 wt, and t11 on a 7wt. Those are about 3/4 of half the head weight. Full disclosure for tips like that I like using one of my Meiser MKS rods that have a very stiff tip and flex further down the rod which can make it a breeze. I can imagine that there are some rods of equivalent wt whose actions make it harder to cast those heavy tips.

Those lines, including the FIST which is a bit easier to cast than a standard skagit head, can be coaxed into doing heavier (either longer or denser) but, at least to me, it becomes a lot of work with narrowing margins of error. Not pretty, even by skagit casting standards.

Yeah, he probably means something specific, but I’ve never heard any of the “rules” related to the issue called that. But that doesn’t necessarily mean I don’t have a hole in my education on the subject. The term might be in the Al Buhr line design booklet and I have just forgotten. Or maybe it is just some terminology used by him and a few people.
