I have the 320 mounted on a Penn Slammer and I like it, but just can't keep the insert in that rod tip guide. I'm going to buy a heavy duty eye for the end and replace the factory one. This is the 2nd rod that's done this. I won't buy anymore of the slammers. Their boat rod (can't think of the model right now) is basically the same action, but is a much tougher rod. I like the slammer though, except for those rinky-dink guides.
