I've been putting my bag together for this one and played my first all 159.9 class round on Tuesday.
Here's my lineup right now:
Drivers:
150g Star Teebird (ultra-straight just like any ol' Teebird)
158g Champ Glo Leopard (slightly understable control driver)
Specialty:
159g CE Firebird (utility shots galore)
149g R-Pro Xcalibur (Its pretty flippy and I only really use this for 17 and back door turnover on 18 - we'll see if this thing isn't taco'd by tourney time! All it will take is one tree methinks
)
Midrange/Putting:
150g dx Birdie (upside-down putting and awesome as a floaty jump putter)
159g dx Zephyr (all sorts of straight/turnover approaches)
Definitely my main weakness is the 150-250' range because neither the Zephyr nor Birdie can handle strong approaches - I still need to find a putter that can handle some snap! My drivers feel totally solid though, I don't think I'm going to change a thing there.
