The only Heritage I had re-fretted was my H157. It was a custom order with several upgrades, but the tiny frets were my least favorite.
I had it re-fretted by Gary Brawer, one of the best guitar techs in the SF Bay area. He followed my request for "no nibs".
The end project came out fabulous! Each fret end has a rounded (hot dog) shape and the guitar plays superb.
Not sure why more guitar builders don't offer this as an option.
