I try to purchase as much as possible from the one golf store in the region. I don't mind slightly higher prices - and they are sometimes very competitive. They usually make up for it with information. But if their service starts to suck, there's no sense doing business with them.
I plan on buying new grips this year. The shop doesn't carry Pure grips but the owner told me he could order them, sell them for the same price as the internet, and still make a profit. Why wouldn't I get them from him?
I don't like to go there unless I'm going to spend money, even it's just a few bucks. I don't want to become that guy who just goes to a shop, asks a bunch of questions and leaves without making a purchase.
I think that is old advice and I hope it's on its way out of golf instruction.
Bounce is glide and forgiveness. My lob wedge has 22° of bounce and I trust it more than anything from the firmest of lies.
It's bogus to say, IMO, that you want less bounce for situations. Plus, the same course can have firm areas, soft areas, etc. Bounce is forgiveness.
Plus, a lot of the clubs with less bounce have wider soles, which limits flexibility.
