Why the need to try and fix something that isn't broken. LEAVE IT AS IT IS.
30 "randomly chosen" members of NSC want it round. Therefore it will be round.
As long as it looks good, I don't mind. However, I would add that a round badge would not look good on this season's kit.
You need either all blue are thinner stripes for the round badge to work.
Personally, my favourite kit is the blue shirt with white sleeves from the 60's but I do not want it again, or the all blue, all the pinstripes or the round badge or the brighton/hove crests. They have their place in our history and play their part.
Lets do something new if we must change it at all!
