I've read a few places where people have said the ultrex shaft is about 3" longer than the fortrex, in the same rated shaft lengths. Is this true, and would somebody explain to me where the extra is gained? It's not making much sense to me. I'm currently running a 52" fortrex and looking to buy an ultrex real soon. 52" isn't needed at the local lakes usually but it definitely is when I go to KY lake. I have planned on just getting the 52" ultrex, but if there is truly more in the water on the ultrex then a 45" would do fine for me. Thanks in advance.
