Apparent success with the R15 driver mod propelled me to do the same the 3 wood, another club I'd dreaded. Set the goal at reach of up to 260 (with roll) and tune for accuracy over distance as needed. That'll be an option off the tee into tight fairways, and something I can also snuggle onto the green on long par 5s, or when I mess up something shorter and need length to try and recover.
In Golf Disneyland, wishes are granted immediately, so straight onto the net via the phone at the range and then off to the shop.
No reason not to go with the R15. Double check with Shiels and Finch. Find an almost new 15 degree X-shafted one at Second Swing. Trade in my "tink" driver (just learned about that), back weight (lead tape is in my bag), dash to Vans to cut to 42.5" and grip with Winn wrap medium, stretched.
Had to think a bit about the back weighting, and did a variable gap wrap of the lead to reduce the amount of back weight. You smear the lead down so it's all smooth before it gets taped and gripped.
Off to the range. I block it a bit, but it flies solid and it feels great. Needs a bit of work to hit off the deck and get the 260, but occasionally do that already, so it's a good starting point.
We'll see how the incumbent Mizuno hybrid 19 and 22 degrees settle out once I can hit the 4 iron solid and reasonably master the 3 wood. Bit suspicious of the Mizuno's cuz they flew good when my swing wasn't sound. So as the swing improves, not sure what'll happen there. What's clear is that rockpile work is now focued on MB and the new (used and hacked) driver and 3 wood, and work towards the rest from there.
