thanks for the reply Matt...
Grain "window" is as follows :-
140 - 280g
Which means little to me
Don't get bogged down by the technicalities Rob.
The original Skagit rods were very through action. They cast a line a bit like flicking an apple of a stick. Flick/lob. It isn't pretty, but it works.
The easiest way to work out if a line suits your rod (any rod) is to get an old double taper line one size heavier than the rod is rated for. Work the line out to a comfortable casting length and cut it right at the tip of the rod. Cut it exactly at the length you have outside the tip that you feel comfortable with holding it in the air during the cast without any forced athletics.
Take that length of line, coil it up and weigh it on a letter scale. The reading in grammas or grains is the weight of line you need for your rod. Write the weight down and keep it in a safe place. You will always be in no doubt about what line weight suits the rod, if you follow that simple method of matching line weight to rod.
Armed with that knowledge, it is a simple job to buy the correct weight of Skagit line, or better still, make up your own custom Skagit lines by splicing line sections together to arrive at the overall belly weight needed to load that rod efficiently, or any other rod you own.
