My congrats to your promotion, and the company certainly appreciates your need for better stuff!
Track length changes, and the game's conditions may change, but the green speed stays "very fast", as for Tour Pros. But, due to the longer approach shots, the balls will roll more on the greens...
"Random shot lengths" have been reported for a while - they may or may not be part of the "advanced" gaming experience (depending on the efficiency of your
tin foil hat).
Having said that, the best hint may be "practice, practice, practice!", and include shot management.
Also, you might consider to change your ball if you dare to leave the costly "low level, slow meter" track: The L11 Srixon has slightly better dots at a considerably lower price, and the L33 Callaway is much better while still less expensive. You might also try out the various WGT balls...
Next stop at the Pro shop: Wedges and (perhaps) a driver - L48 is promising while L46, L50, L58 keep to the budget.
And, most important: Have fun!
