My guess for the next free rental is Master's weekend, but who knows.
Good advice on the clubs, except that a mixture of wedges - chosen wisely - is o.k., since they all have about the same swing speed.
My prime focus is on the low end of the wedges. There should be a short one of 50 or 60 yds in your bag to ease the short game around the greens. Next, make sure a nice and even spacing between your wedges below the PW. Including the punch shots, this provides a bunch of options.
Of course, quality pays off. The top products of Max, Cleveland and ATV have their followers though being a tad pricey.
Plus, there may be a chance of amelioration in the ball. I suspect that "Hack" Max ball to be expensive for being slow and available early but not to have the best overall performance for the money. For example, try the L33 Callaway!
