Hi Slinx, just saw this post and surprised there were no replies (but when I saw the title I thought, not another begging thread lol).
I see you have upgraded the driver - I haven;t used that R1 but have seen others use it and it flies!
As for Irons, yes the G20s are very good and are higher trajectory, so help hold the elevated greens a little - fine from Masters Tees but they struggle from legends approaches. The Bladez are the next step but are a faster meter.
On meter speed, the better clubs have a faster meter, so at some stage you will need to bite the bullet. I went the same route using only slower meter clubs, but eventually if you want to improve, it is required, so do not let the meter speed deter you - you do get used to it (and slow meter balls help!)
Just a thing on levels, at you stage if you play daily (and you can do this by playing 1 hole under the WGT Community - Courses and select a hole), it does not take long to progress through the levels - looking at your join date, you have not played regularly.
The wedges and putter I concur, stick with them as they are fine until later.
As to the last part - I used the starters clubs for a year until I made master - now I would play as much to level up, get the R1, probably the G20s. Then I would play ranked games LOL - oops I laugh but some do this.
Or I would get the R11 set earlier but the one thing that would not change is, I would still love every minute of it.
