That’s a terrible example. Since you used Tesla as some sort of unrelated example, let’s use Tesla in a hypothetical. What if Tesla’s top engineering teams left Tesla and went to work for Bobs Motors, a new startup specializing in electric cars. Would you say, oh well they’re so far behind they’ll never catch up to Tesla?
I just looked at Dicks Sporting Goods (probably the shop most casual players are buying balls at) and the Wilson Staff ball is the same price as the ProV1. https://www.dickssportinggoods.com/p/wilson-staff-model-golf-balls-20wsfustffmdlwht1gbl/20wsfustffmdlwht1gbl
You can also get ProV1s at a pretty nice discount too if you wait until a certain 2-3 week period on March/April every year.
You say PXG makes good clubs make “that isn’t enough to take over market share.” I think it’s pretty clear from this forum alone that they’ve gained market share, particularly over the last year. You certainly see a lot more PXG clubs in college and amateurs bags now too as they have bag and club deals with several very good college golf programs (SMU, Oklahoma, Oregon, Washington, Vanderbilt, Arizona to name just a few). Personally, I had almost every new Ping driver release going back to the i20. The Gen4 0811X is a better driver for me than the Ping G410 or 425 at almost half the price.
