Not @gregv but another who has "worn out" my hands from decades of gardening, typing, sewing, remodeling and arthritis.
I have had both CMC joints done using the tightrope approach, several years apart and by 2 different surgeons. My thumbs continue to hold up today - one is about 6 years old, and the other is 15. They have full sensation and range of motion and good grip strength. I only wish the rest of my hands felt as good.
Why did I choose the tightrope? Shorter healing time and the potential for longer success.
My current shoulder/arm surgeon was surprised I had the surgery from the superficial appearance of my thumbs.
