I think the Nextcast chart on the Coastals is wrong. It recommends, for instance, a 575 for an 8wt. in BOTH the integrated tip line, and the non-integrated line to which you add a tip. How can that be right? The F24 has an integrated tip, just like a base skagit to which you have added a tip. So the weight recommendation can't be the same for each--makes no sense. I questioned this in a previous post, and a person familiar with Nextcast said the charts were wrong--and were to be corrected. Never happened. On all the other integrated tip Nextcast lines, like the SalarFinder, the integrated tip and non-integrated tip lines have different recommended weights, as they should be.
So I guess what I'm saying is this--with the integrated tip F24 line, I think you need to go heavier than you would for a basic skagit to which you add a tip, to get the same load.
If my logic here is wrong--please help me understand it better.
