All of my Ruger SA revolvers are Bisley gripped and checkering would offer a better hold, but I have smoothies on mine nonetheless. The traditional grip needs to roll in the hand to shoot comfortably so certainly a smooth grip would do better there. I've tried the traditional style but didn't care for that form, YMMV.
