Linq to Sql for Membership, role, and profile?

Quick question, would it be wise to use Linq to Sql / Linqdatasource to manage data in aspnet_Membership? I also have role and profile enable and needed to be manage too. I am not sure how would I manage the profile data using Linq to Sql.

Basically I am creating something like Website Administration Tool to allow administrator to maintain membership, role and profile for users.
