If you have to "contact" them in order to get a price, chances are they're going to be pricey.
(With the odd weight distribution I'd be looking at getting a bonnet that would be heavier than standard so there was a uniform spread of weight at the front. Sure it looks good but I think getting one to make the front end even lighter is a bit like shooting yourself in the foot because holes are "in" this season)
