For 99% of the people rebuilding their engines, they are looking for a counter-weighted crank. Yes, the non-counterweighted crank can be used in conjunction with a lightened flywheel to reduce rotational mass and increase track performance. However, by far, these applications are rare, and many people don't feel comfortable building a high-reving engine with a non-counterweighted crank.
Despite the weight penalty, I believe that most of Porsche's (if not all) racing engines used counter-weighted cranks...
