Just picked up a 2016 Kahuna 900 at half-price - now I know why. Assuming it's just a sticker change, I can live with that for a season. I very rarely look at Grade 1 or 2 willow so was happy enough.
Sorry I didn't go custom by the way, but playing cricket in 3rd or 4th XI I can't justify the expense...
I've had a few quality Kahunas off Vitas over the last few years, some others I've seen can be a lot more concaved for similar weights, so performance can vary, but the ones I've had have been guns. Hope yours goes well.
Custom doesn't have to be expensive I had a quality custom X3 off Redink a year or 2 back, and just put another order in.
