use linkwheel if your not satisfied anymore. The key there is get a lot of links from different method. Schedule your worker or yourself in building links.

Monday- angela/paul- forum posting, web 2.0 profiles, etch.
Tuesday- linkwheel
Wednesday - article submission
Thursday- link directory sub
Friday - blog commenting

Its just a tip if you think you need some other source of links. But if your think profile links works for you better then continue your journey and don't bother doing any other method. Cheers!
