My progression;
Clubs - 33 Ping Raptures and then the 59 G20's.
Wedges - Ping, then a Cleveland and waiting on the 86 ATV.
Putter - Ghost Spider then Nike Method
In hindsight if I were to do it again I would probably do the following with 5,000 credits.
Level 48 Ping Full club set - 3,295 credits
Level 55 Rossa Putter - 725 credits
Level 42 Ping Wedges x 3 - 600 credits
That totals 4,620 and you would have 380 to play with some different balls.
Another option I would consider would be the Level 48 Ping Rapture Irons - 1,685 and the Level 48 Taylor Made R1 Driver - 2,495. You would then have 800 credits left and would have to decide on the Rossa putter or the 3 wedges.
****Also rather than spend the $50.00 directly to WGT look at the partner offers. I have yet to give WGT money directly but there are options to get better credits through merchant offers....Bidz.com got me I think 3,700 points and my wife got a nice watch for christmas, also clothing offers.
$5.00 on a web name through godaddy will get you 2,700 points.
Just some ideas
