Which womens Burton snowboard boots to buy?

Hi
I'm thinking of treating myself to a new pair of womens snowboard boots (I'm an intermediate rider). At present I have Northwave Dahlia boots (mid range flex rating 5) but think it's time for a change - a narrow fitting boot will be no good to me. Anyone have comments/recommendations on Burton boots? (I prefer the ones with the speed lacing system not the boa ones)
Thanks in advance for any help.

I've no experience with women's boots coz I'm a bloke but plenty with my own boots and the only advice I'd give is try them on. You can read forums and advice on boots until your blue in the face but your feet are individual and different to someone else's. Great tip though, when you do get them invest in a pair of superfeet insoles. Around £30 but worth every penny. Hope it helps a little. You won't get much boarding advice on here. Ski Central. ;)
