Hi Dan, (I excluded the first part of your user ID as I do not want the political correcteness lobby after me) I agree with Alosso that the level 59 G20s do not have the stopping capabilities of the upper level G20s
I understand what you say that the dots are the same (bar precision) but as a player who used both sets I can assure you they are not. Possibly the upper level clubs have an even higher trajectory therefore allowing to get more bite.
When I used the Level 59 clubs, a course like BPG I had little chance of attacking some pins, so I reverted to using a Nike to see the difference - it was negligible as the clubs just could not create the desired spin. The upper level G20s were a huge improvement - but the R11s were a massive improvement, and all using the Cally.
The other major factor is distance, using the lower level clubs and playing approach shots from legends tees - clubs 3-5 irons are hard to stop quicklly, especially to elevated greens - and I found the balls,made little difference.
So again back to Alossos advice - match balls with clubs, and clubs with levels - or you are potentially wasting credits.
