What kind of tricks those top players do and know, when they play under 60 what I cant understand...its simply over my head.
I thought so, too, until breaking 60 as a TM - once ;)
What is annoying me most, is putting.
This requires practice, and practice, and some more. Support in calculation may help - I use tables of meter power over length, by green speed.
Outside E Tour, you might also consider a replacement for your low level putter, and custom balls will reduce the meter speed (even the cheap ones at 10 cr).
There are other, tiered tournaments with lower green speeds - plenty of source for experience!
