Hi- These were installed briefly on a Carvin SB5000 34" scale string through cut 4+1. The Half Rounds are closer to flats than rounds and the Pressurewounds are much closer to rounds than the GHS description lets on. I little stiffer than D'Addario Nickel Rounds, I love them and will be putting a set on my Lakland. So a holiday string smorgasbord sampler platter for you $12 ea. $20 for both post paid.
