Single length is basically an equipment frenzy right now - that I haven't seen in my 20 years in this industry. If we are out of stock of anything SL it's because of the popularity. I don't anticipate it dying anytime soon, and even if it did, we would still specialize in it with regard to the Pinhawk brand. It was born in 2010 when not many cared about single length, and it will survive long after the frenzy dies down.
Our single length fairways just now hit the mainland and we look forward to that release within the next couple of weeks. Early testing has been excellent and folks are going to love them.
