I guess if truth be known, the type of 'normal', everyday use we put our rods through will not allow an excessive line strength to snap them. As Ian said, the clutch on his reel is 'silky smooth'....which says it all. Backwinding or using the clutch when required will stop the rod from snapping, however strong the line is, simple as that. It is only when you are in a 'hook and hold' situation that overly strong line
may break the rod.
The other point that struck me was this...what set of 'numbers' was the recommended line strength the makers put on some rods based on? The ACTUAL breaking strain of the line....or the nonsense most manufacturers put on the box and spool label?
If it's the latter, then the figures on the rod are based on inaccurate data, whereas if it's the former, most anglers will be inadvertently overloading their rods anyway....which again makes it a nonsense.
The fact is, all these numbers...the test curves, stated line strengths, whatever...are usually wildly inaccurate garbage. So, either the manufactures start getting things right (or in the case of test curves, come up with a system that works)....or we carry on making our own decisions on what rod, and what line, to use. sounds good to me
