Boy, looks like data shuts the topic right off! Ghoti, I'll take your comment on rare disagreement as a compliment. From an expert like you, it certainly is. Gonna nail some big smallies tomorrow. A 6-10 on Friday, thought we saw some over 7. But they aren't 7 until you weigh them.
I have to strongly disagree that they mean nothing. I've used them many times and found the direction they sent me was right on. CCS is the ONLY subjective measurement of what I will call "usable" power/action in blanks and rods. By usable I mean what lures do they cast well? Which blank has the softest tip? How do they feel? Since "parabolic" seems to be so important on this forum, which blank has the most "parabolic" action? Etc.
I don't consider loading a rod until it breaks to be relevant for anything other than lifting an anvil. Ghoti, you say it's only good for comparison. But that's valuable. Say I have a St Croix SCV70MF and I like it. How can I get a similar blank now that St Croix isn't selling? I test others and find one that has similar power and action numbers, and I assure you, it will feel very much the same. CCS is very valuable.
