I'm 33 and I tend to lean towards the pro combat jerseys. Simply because I think they look better. I don't want kind of drastic overhaul, but I do feel that they're a more modern version of our traditional look.
I tend to take the attitude of nothing stays the same. The look we're so used to now was probably thought to be a blasphemous by a portion of our fanbase back then as well. They switch to the pro combat look and 15 years from now we'll be saying they shouldn't change from it to something else.
That's not to say I don't love our current uniforms or would be upset if we didn't make the switch. We really can't go wrong either way imo. Just avoid doing anything crazy and we're golden.
