Bonnet raisers - Not everyone's cup of tea

[aaron_one]

Right I decided a while ago after grossly hating them, that I like the look of bonnet raisers. I've read a few bad things about them and a few good things.
Basically I'm not going for any performance gain such as 'getting more cool air to the engine', more just for the look. I have a hdi and was wondering the ups and downs of putting bonnet raisers on, any problems and where/which ones to possibly get.

Thanks guys!
