The tour starter set is very nice, and worth any upgrade. However, only the upgraded drivers beyond this seem worth buying. I broke down and purchased the Taylor Made Burner complete set to upgrade my Tour Starters, expecting the increased spin and slight increase in distance on the irons to be a big help.
First of all, some of the irons actually have LESS distance than the Tour Starters (i.e. 7-iron). Plus, because the trajectory is lower, the increased spin doesn't make the ball stop any quicker (except for the wedges). In fact, the ball seems to roll even further on most iron shots. The biggest problem is the "forgiveness" in the graphite burner irons (rated at '3') is much worse than the forgiveness on the Tour Starters (rated at '3.5'). On the swing meter, the colored "good" area is about half the size and miss-hits seem to be amplified by a factor of 3. This combination makes the burner irons, which cost 900 credits on their own, seem WORSE than the Tour Starter irons, which have a higher trajectory, stop quicker most of the time, and are more accurate. What a waste of money.
The rest of the Taylor Made Burner series has the same problem as the irons, but I can live with the driver and probably the 3-wood accuracy because I'm usually not aiming for the flag. I wish I would have saved my money and just upgraded the driver.
