Wilson .... doubtful. Just because the one guy who plays those irons happens to win the US Open, doesn't mean they are on a comeback. But time will tell.
Titleist irons ... look who you are talking to!? I'm the biggest Titleist homer E V E R! So yes, I like the irons. All except for the T300 (AP1 replacements) which makes sense because I've never liked the AP1. Now the T100 (AP2's) or the CB's or MB's .... now these are money! I will game any of those. I definitely see a combo set in my future. Titleist Thursday's are going to be fun this fall.
Music on the course .... I don't care for it honestly. Call me a purist, or whatever but music has no place on the golf course. If you like only Country or RAP, and that's all you listen to ... why would I want to hear it, especially if I like Classic Rock? Bottom line is you're not going to make everyone happy. There are bound to be people in your group (or even in the fairway over) that don't want to hear your music. If you insist on doing so, be kind enough to turn it down if someone asks you to. Or turn it off at tee boxes where everyone can hear it. Not sure everyone wants to tee off with N.W.A. playing in the background. Just don't be a Richard about it.
