I still think it's ludicrous to artificially beat in a disc.
Lose your ole' trusty? That sucks A LOT. At the same time you (royal you, no one in particular) should be capable of manipulating the other discs you own to cover that spot. No artificially beaten disc will replace your old friend. They just won't.
Flippy Z Buzzz and Meteor were mentioned earlier...if you need a temporary replacement just buy one. Or don't throw your super necessary discs on holes you may lose them.
I'm a young old fart at this point, if I lose a disc I deserved it and move on. Not old age but old at disc golf. Idk just rambling I'll shut up...
Not to be a jerk, as well?
It must be nice to be you. I've played something like, I dunno, 400 or more rounds, plus many hours of field work, starting as basically a noobie a little less than 2 years ago? And I still don't really know what a beat-in disc really even is. Sorry I'm bad. Sucks to be me.
Some of that is likely plastic addiction. Some of that is discs not working for me as my form and technique change but are not anywhere close to mastered. Some of that is figuring what molds I like. Some of that is molds I like not being available when I need them. Some of that is losing discs that were my most thrown. Some of that is not really liking to throw base plastic discs (ProD, DX, Prime, they all just feel bad in my hand.) Some of that is, early on, not wanting discs to beat-in quickly, as I didn't think I wanted the discs to change on me while I was trying to learn, which was another reason I gravitated to things like GStar and Gold line.
And I'm definitely nowhere near good enough to take an Envy and make it fly like a Zone. And I don't know what making a new Zone fly like a beat in Zone would even look like.
I've get plenty of means to get new plastic. I don't see the harm in trying to approximate a well worn disc. No, it won't be the same as a 10 year seasoned champ Teebird with a thousand or more rounds on it as your main thrower, but it will be closer than anything I've got.
