as long as you tune it just a little and test it you should be fine..just keep doing it until you get it where you want and if it gets to flippy just tune it back up again..but your right ...it shouldnt be done to much...use moderation lol
I leave mine on my dash. Even when not 100 degree heat it softens them up. HOWEVER I do this before trying to beat it up. The heat softens it making it more maliable that way when you throw it it beats up more than if it were cooler.
Heat it up then go throw high thumbers into a field OR bend in hand (not to much) and try to loosen it up. I myself will just forehand them or backhand them right into the ground in front of my. Does the trick, pretty quick.
I just throw mine at every hole as an extra toss that doesnt count, do that a few times and mix in a few thumbers and you got your disc beat to perfection! I have never tried to "tune my own disc", however it couldnt hurt to try so next time Im gonna see what thats all about.
