Try reading that. DG Rod Works
All you really need to do.It's very easy,if an idiot like me can do it i'm sure you can do it too.
It does change your rod action a little bit,but to be honest not enough. I broke one of mine and now i like it even more.It made the rod action seem like an extra fast instead of fast.I've gotten better hooksets now on the rod. I've heard of people buying 7' rods and breaking the first tip down to 6'9" with a faster tip bend.Sounds stupid when i first heard somebody doing this.I can honestly say i understand why now though.
I stock up on the rod repair kits just in case it happens again to another rod.It really isn't that hard.
