Are you loyal to a specific brand when it comes to rubbers or are you willing to switch brand every time you want to try some new rubber?
Me, I'm pretty loyal to JUIC rubbers when it comes to inverted rubbers cause they have all been high quality so far and staying with in one bran makes it easier to compare current rubbers to future rubbers as they are all in the "same scale", if you know what I mean.
When it comes to pips/anti, I'm as disloyal as they come

Anti, simple because most brands only seem to carry one anti and pips... Well, I feel that different brands are good at different things when it comes to pips.
Also, which brand do you think have the most loyal followers?
My guess is Butterfly as it seems there is a bunch of people who don't mind paying their hefty prices to get their brand on their stuff.
