So I have been playing a ton of winter golf this year. And the plan was to try out a wide variety of discs so I could have a general idea what my bag would like once the weather got nice again...
But Vibram has ruined plastic discs for me. They all feel slick and uncomfortable and just plain wrong in my hand. Even on the warmer days the plastic discs just don't feel as good in my hand or feel grippy. And on cold or wet days, they dont grip at all and just feel terrible.
I was really, really trying to give other manufacturers a chance. But bravo to you Vibram for making the best feeling/grippy (even in adverse conditions) discs. I do not foresee myself switching away from an all Vibram bag anytime soon and possibly ever!
