Hi, Glenn.
I'm no expert. I've just made Legend and I'm really struggling, but this my opinion on your equipment.
You've got three wedges which is good. I would get the new SLDR driver (lvl89). It hits long but is more forgiving than the R11. I would get the R11 irons (lvl89) or if the meter is too fast for you then get the G20 (Lvl83) set. I went from the G20 irons and I'm starting to get use to the R11s. Putter is a personal choice.
I would use the best ball you can get. I use the Nike (lvl71), quite expensive, but they hit long and slow the meter down.
