Oh, also threw these, ranged from pretty straightish to very understable for me, eeeasy distance; threw the most understable one like 430' the first time touching it with like 80% power, went way right of my intended line though.I fondled some Tone discs the other day, they're pretty weird. Feels kind of like an undermold, so to speak; the entire underside of the rim seems to be made of a different plastic blend.
I'm not sure how it'll hold up, I could easily see it coming loose after a few rock hits, but I'm sure time will tell.
My friend who threw a few said they flew a bit more understable for him, but his technique isn't the best.
