Shooting heads DIY
AFTM system
By Martin Joergensen
This table shows the different AFTM classes and their corresponding weights. The AFTM system sets the standard for the weight of the outer 30 feet or about 10 metres of the line. This will normally be the belly of a Weight Forward line and some running line, but the number also applies to Double Tapers.
When calculating the weight of a shooting head, you can use this number as a guide line and increase the weight for a given AFTM class. The right side of the table shows suggestions for this shooting head weight. On top of that I personally prefer even more weight, and for demanding conditions like long casts under windy conditions I go two classes above the AFTM class. Each rod has its own performance, so you will need to test and adjust individually under all circumstances. Read the article.

Please notice that the above recommendations are just guidelines. I personally often cut my shooting heads slightly heavier than what this table recommends. Martin.

Did you find the above interesting? | People who looked at the above also looked at:
Section: The sound of The Global FlyFisher
If you look in casting books, ads for fly lines or just the odd fly fishing magazine, you will often see some fascinating pictures of casting. Lines forming the most beautiful arcs in the air, clearly illustrating one of the mesmerizing things about fly fishing: the beauty of the cast.
Section: The best fly patterns from all over the globe
This is a very simple fly imitating the caddis larva. Some may call it realistic fly, some will say impressionistic, but no matter what, the originator says with 100% certainty that it\'s a killer pattern and he has caught lots of fish with it in many different places.

Loop do a table of length of head of their custom series vs. length/AFTM rating of rods which should be available on their website - unfortunately they don't specify weights. Can anyone help in that regard?
