59's are going to be middy, I would go with something Alnico II line that would be more agreeable. I love the 59's I have in the chambered/semi's but I think I would go for something in the II's. If you do use the 59's lower them a lot.
If it were mine, Id go for Seth Lovers. I like the 59 in a semi or solid body. 57's might even be a nice choise in a full hollow also.
