Rotating Board Racks...for XS tower

I keep my boat at the lake in a covered dock - rotating racks are really helpful, otherwise you would need to unload the rack before pulling into the dock. So far, the choice seems to be Titan - which is over $500 for a single board rack. Bullet Lines seems to have some options for either combo racks or a double surf racks at a pretty good price - has anyone had experience with their rotating solution? Nice makes double surf rack - but it looks like if you price the rack plus the rotating option - you over $500. What do you have and what do you suggest - last thing is this needs to go on a Illusion XS tower. Thanks - I would really like to get something as soon as possible.

keep an eye on sky ski. they are working on a spinner attachment that will work with your existing racks and from what I am told you can afford spinners for all your racks for that price..

I know of another rack co. working on a swivel surf rack as well, should see something late summer, early fall
