And the point the caster is trying to make is????????

The ferrules would loosen if it was cast like that for any length of time. I've unfortunately loosened bamboo ferrules but I am typically casting high end graphite fast action rods of 10wt and much higher for the salt. My poor little 5wt boo just wasn't happy with my water hauls and SW casting techniques so I had to send it back to the doctor to be fixed. Learned a lessen very quickly that way. I now hold my boo's with my index finger on top of the rod as a reminder to not cast it like a SW rod.

In the SW world dumping full lines is commonplace and no real big deal.
