Personally, I think you should play with what you can realistically afford.
Currently, I have a TM Bubble Burner reg shaft, 9° driver that I got from a bargain bin in a pro shop at some course somewhere for $20 about 5 years ago.
Up until very recently, I struggled to consistently hit the club and I had been thinking well documented thoughts about not hitting driver at all.
Then, someone on here said something that seemed to make some sense, I took that to the range and hit some drivers and crushed them all and now the stick is back in the bag for good. The 3W has also earned a reprieve from the shed and is back in the bag as well.
Over here you can pay upwards of $500 for a driver. Again, personally I can't see the value in that sort of purchase, especially when I have not even paid 2/3rds of that amount for all the other (12)
clubs I carry in total.
All the club manufacturers will tell you their current driver will add yards and accuracy to your game. IMO that's twaddle (a technical term for garbage)
That said, I would dearly love to purchase a full set of the current
Ping product, but realistically that is out of my financial reach just right now. Further it is arguable that the purchase would make me any better than I am right now anyways...
Bottom line, IMO do whatever you can afford and so long as it works for you, its all good...
Cheers
