I play with my modern clubs, and sometimes with a set of hickories. Additionally, I've been thinking of picking up another set of vintage steel shafted clubs (circa 1950s-1960s) to "practice my hickories" at the public range with less fear of breaking a hickory shaft on a range rock.
Right now, I have my hickories listed in my golf bag, but it makes selecting clubs frustrating because now I have two 5-irons, two 7-irons, etc. Even with the custom names I put in ("Hickory Niblick", etc.), the big circle logo is still a "5". Anyway, seems like it would be a decent feature. I can't be the only person using more than one set of clubs.
