I like
Hayley, and this spelling only too. I think it's pretty dated. I knew a couple growing up, but most would be a little older than me, so I see it more 80s than 90s, at least where I am. Using
Hayley in 2012 wouldn't sound fresh and revived, but more kind of... a little off. I look forward to a
Hayley comeback!
Hayley is my favourite and most intuitive spelling.
I would assume the
Hayley spelling.
