I'd definitely wear my ACC kit much more often if it looked something like that - but my taste isn't everyone's. Nothing seems to divide opinion in the club more (see previous posts on this topic ad nauseam). Even if we were to get the design changed there's no chance of pleasing all club members: what I'd be happy to wear, someone else might hate. Add in the expense of replacing perfectly good - even new - kit, and the motley appearance of the club run while the changeover takes effect... It seems too big a problem.
The present design coincided with the membership boom, making any change now far more difficult to manage. I think it was looking dated 5 years ago, was a colossal missed opportunity - is plain ugly. But that's just me, and I think I'm in a minority.
