I have some questions about these dvds,I appreciate all the answers.
1.Is roadrunner cull a whole different type of cull and Cullfather teaches the standard cull or roadrunner also teaches the standard but Kostya Kimlat gives tip on how to execute it faster(and how to cull multiple cards)?

2.Generally,what types of cull there is?I know the standard cull is the Hofzinser spread cull,what are the "nonstandard" culls?

Thanks!
