Well I guess if I had 3-5 discs I would not even worry about a bag, grocery bag, 6 pack carrier, whatever... but to carry 15 discs around and try to have crap all in my pockets(tape, mini, water..etc) no way. Bag is needed for me.
I see a lot of one disc players (no bag) out on the course. Seems like a simple way to play. But I'm a pack rat. I like to bring everything but the kitchen sink. I need a place for all my stuff & pants pockets wont hold it all.
Perception-wise when I see someone with one disc or no bag I figure they are probably new to the sport.
Yeah, there is nothing worse than setting down like 10-20 discs each time you throw then trying to pick up that pile every time after you throw. I agree with Eirik, you need one to carry more than 2-6 discs and carry a drink and do it comfortably.
i used to make fun of people who carried a bag. now i carry a tour bag with 25 discs and all my other crap: tape, drinks, score card holder, rolaids, knife, flight chart, cigs, wallet, phone, towel. i just couldnt get used to havin to carry alll that in my pockerts or not at all again. i think havin a bag is the way to go even if you only carry a few discs, still could always use the thwe beverage holder.
