I used the starters clubs for a year and with the exception of an upgraded driver, made it to masters (average 67 or under for masters). Then I had to upgrade. It was tough but was possible and therefore feasible still being TP regardless of level only using the starters clubs.
What gets me are the players that never play RR, have high level clubs and are pro or below but it's not against the rules. All they do is play A/S or Blitz so doesnt hurt anyone at the end of the day. Personally I would be embarrased to do so, but thats jut me.
