nongolfer

I'd really appreciate any help here. I'm attempting to choose a bag for someone else and am unsure of what type to go with. Their membership this year includes a power cart, however, if I get a cart bag and future years they don't have the powercart, I'm assuming the bag will be useless? Is a carry/stand bag ok for a powercart? I obviously know nothing about golf. Would also like some recommendations if anyone has any. Thanks for any help.
