Most gear is a balance between speed of meter and distance. When im tired i change my gear for a slower meter and a few less yards. I've seen winners of Open RG tourneys with the L29R11 Driver. Maybe they're cheaters, but just as likely (more than likely) they are hitting more fairways and have the irons or distance balls to compensate.
If yr really concerned about advancing levels, wait until u have 15 or so consecutive days, do surveys for free credits and buy booster drinks at the start of each days play. It got me thru the Lvl 70s quick.
