I just got a Cort Curbow fretless. The fretboard is a synthetic called Ebonol. I read somewhere else on the boards that the synthetic fretboards are much harder and more resistant to wear. I love my rounds but I'm a little wary of fretboard wear, so I wouldn't be too opposed to giving some TI flats or D'addario Chromes a try if it would cut down on fretboard wear drastically. I'm open to pretty much any suggestion that will help me narrow my choice of strings down. If anyone has any experience with an Ebonol fretboard that would be great too!
