Maybe for some. For me if I don't have a nice shiny ball from a brand that I really like it works in my head and effects my game. If a K-Sig is that ball great. I also get a ho itch every now and then and needed some white balls anywho so I snagged 4 doz. K-Sigs a few months ago but haven't played since. So, for me is isn't just a ball. If the K- Sigs don't work for me I will re-home them. I have a bud who will find a muddy ball on the edge of a water hazard that has been submerged for months and play it without cleaning it. He will complain about the performance but keep playing it. He has dozens of new balls at home his kids give him for presents over the years. It's whatever suits you I guess.
Interesting note. I see the KSigs on Lostgolfballs.com now.
