I just finished assembling a Glo Bag, that is, a separate set of discs in its own bag to be used just for Glo rounds. This was a fun.
It has been a few years since I glowed. In the old days it required glo discs and a black light or camera flash and was, quite frankly, a pain. Only a few models of glo discs were readily available and they glowed with various degrees of brightness (some barely at all). With so few choices I needed to manipulate my game to the discs, making do with what I had. It reminded me of being handed a few items of clothing from someone else's wardrobe, where nothing fit well: the shoes were way too small, the hat so big it fell off, the sleeves went past my fingertips, etc.
Playing with the old glo discs was also frustrating. The brightness was so poor it was hard to follow the flight of the disc in the air, making the search on the ground too much work (glos still stick out on the ground when you get close to them but if you have no idea whether your drive flipped or hyzered it leaves a lot of area to search).
But now with the tiny glo lights that tape on a disc, any disc is suitable for glowing. The lights work so well, it is easier to follow a lighted disc at night than it is in bright daylight. Even landing in a pile of leaves is no problem as the light shines out.
My local club has a glo league on Wednesdays which uses a particular course configuration. So prior to taping lights on discs I took a stack of back up discs out to test various choices on on particular holes, in short, I held try outs. Then once I had picked out a full bag (18 discs) I played a few practice rounds and local leagues with them. After shooting well with the new configuration I feel confident in the them.
The alternative would have been to add lights to my tournament discs. I rejected this as adding or taking off lights is too much work. Glo lights don't noticeably affect the flight patterns of discs but they are still not legal for tournaments and I play in a tournament most weekends. I have gone to a GoCart for my tournament discs and not wanting to trade in and out, I put the glo discs into a Revo Bag.
Being perhaps a bit obsessive, I purposely maintain 2nd and 3rd string tournament discs (back up set ups in case of loss). Only a few of these discs made the glo bag, mostly the ones I want to know better or the ones I want to break in more. Fortunately, having played for so long I had plenty of options to choose from. Being sponsored helps too.
