I feel your pain. I had all my wire rods switched to roller tips because IMO the wire tends to grab on the guide and makes for a more difficult and uncomfortable retrieve. I thought it was the wire and switched from stainless to monel and then to that other mix and nothing seemed to help, then swited the tip and life was good. I like carbide on the other guides though. I just use a tip roller.
They make several roller types. They make a swivel tip roller but it is like 50 bucks just for the tip. And they might even make a carbide roller tip. I opted for the standard roller tip that my shop said all the charter guys use and they replace the roller every year or two (and they use them constantly). I use wire only when I have to so mine should last several years and they are easy to replace.
BTW, I see Tsunami now makes a wire line boat rod....I have yet to see it but I bet it will give those penn wire rods which I have (which are just so-so IMO) a run for their money. I saw a photo of them and I already like the grip. Don't know what kind of guides they have though.
