There are other great builders showing their wares on the Rod Building Forum from time to time but I haven't seen enough of their work to have an opinion.
If you go back through the threads on the Rod Building Forum started by any of these fine rod builders and look at what they have built and / or review their websites and talk to them, I think you will come away quite impressed.
