Back when I was playing basketball during high school , when a noob player uses the "big basketball bag" to store his stuff and brings it when playing, he often gets regarded by more skilled players as a poser athlete or something. The main idea of this weird mentality is that noob players don't have the right to use showy stuff like in this case the basketball bag. I wonder if this is the same in the tennis world? I'm planning to buy a 6-pack Yonex bag because a backpack seems way to inconvenient already but there's always that above mentality. Guys at my club are sometimes jerks who pick on those still in tennis training.
