I'd Suggest the best driver you can handle for your level first, and then Wedges then balls.
Drivers - the Raptures will keep your swing meter speed low for your first few tiers.
Wedges - the Z-Satins - the best you can get for your level.
Balls - GI balls are Game Improvement balls - they slow down your swing meter.
GI-S are for Spin, GI-D for distance.. -SD of course do both.
I don't like the D balls personally as their extra distance isnt reflected in the Club Caddy.
Spin is good as you have more control over the ball in the short game with the wedges.
Once you have these sorted - Dont bother buying more until you are well into PRO - or Tour Pro tier.
As for Irons and Putters..
Irons - again the Raptures will keep your meter speed down. Beware of the ones with fast meters until you are well into Tour Pro level.
Putters - The Redwoods are favoured over most others, however, go browse some profiles of some Masters and Legends and you will soon learn that the Beginners and Starters are popular at these Tiers.
I;m at Tour Pro
Callaway (s) balls - previous loved the WGT GI3-S balls
(Practicing a little lately with the Srixon and my new Cleveland wedges)
R9 8.5 Driver is hard to handle, very fast swing meter. Miss the Ding by 1mm and its a Monster... But when you get the DING it is a beauty to behold. Although probably a little too much distance in these at my level. But I am getting good at 80% and 90% swings. :)
Cleveland Wedges - Hell of a spin on these things and take getting use to. they will stop on a dime and them come running back at ya. Hit them right and they land like a butterfly with sore feet.
R9 irons - i love em, had them a short time and were very easy in the transition from the K-15's, Which served me very Well for a Very long time.
I cant see me opting for anything higher than the R9 irons.... yet.
Putter - I have the Daytona Rossa. I tried going back to the Beginners and the Starters, but.. they just dont have any 'feel' or.. guts to them. I putted worse stepping back to the WGT clubs.
This is just my experience.
