MioKontic: I'm only a Master, but played off the back tees and with tournament speed greens. I only have a 275yd driver, Rapture irons and GI3-S balls. But I still scored -2. I bet that will beat quite a few legends with their superior equipment.
Sorry, but -2 would have gotten you squat in the USGA Virtual Championship Qualifier
You would have needed -6 just to qualify, -4 would have gotten you into the top 250. I'm not sure if the green speed is the same in the current USGA Oakmont tourney - I can tell you the green speed in the qualifier was torturous.
Your equipment isn't too bad, at the time of the USGA Open qualifier, most of the good players were using your driver and one of the best ever, Iconian(AKA wgticon), was using the rapture irons and I don't believe he was alone.
Granted, the open qualifier was unlimited, so keep on playing and maybe you will get to the point where you'll be able to best some of the better players. GL...
