Hi guys,
Yes, I understand why you disagree with me. I think that my suggestion is in line with the standard order of adjectives, while yours is that the idiomatic nature of the phrase requires the two words (tight + corner)to be kept together. So, it's a question of which of these two considerations is the more important.
My feeling is that the idiom 'tight corner' is so well-known that it is not straining it to insert another adjective. In fact, to me it seems to 'freshen up' what is a slightly tired idiom by making the reader think about it for an extra millisecond.
However, style is a subjective matter. I certainly wouldn't want to get into a tight grammatical corner by arguing that I'm right and you're wrong.
Best wishes, Clive
