While I haven't been looking in quite some time, I agree with your approach of being up front with things.

It seems like a "quantity" vs "quality" thing in that you could omit it from your profile and potentially get more responses, but you'd still have to ultimately address your enjoyment of CDing with them, likely to lose the interest of some.

Of course there could be some that might be on the fence over whether or not they'd be comfortable with a CDing partner you might miss out on meeting with your upfront disclosure.

Either way I wish you the best in finding a new partner.
