Rick,
Some opinions on travel.
If you must connect, try to do so in places other than Heathrow. It’s a transfer bag nightmare. Frankfurt is really good I’m told, as long as you book with enough time. Likewise, if you connect in the states, I would be try and purchase flights with more than 75 minutes for connect. Under that and you run a higher risk of the fog and friction of the airline operation hosing you out of your clubs. I booked my recent trip through Ohare with 2.5 hours of sit time. No issues.
Last thing I’ll say, adjustable head drivers, woods, and hybrids are worth it. Not just for the adjustability for your swing, but more so for the safety of you sticks. I don’t know anyone that’s broken a shaft with the head detached. I know lots of people that have broken shafts with the head attached. Cheers and best of luck.
