Old Pockman is antiquated and nearly impossible to solve in under a minute. Too many turns. R2M2 is better though still antiquated, allows for solving times of less than 20 seconds. This can be made more efficient by adding M1 and R1 solves. BH and other 3-style methods are even better and fast and allows for sub 20 second solving times. Freestyle commutators and conjugates can be sprinkled in to make the solves more efficient Then there is 5-style which though hard to learn, is what I think the next records will be coming from because not only is the solve more efficient, but the memo is as well.
The great thing is that all of these approaches can be combined into one very efficient freestyle approach because they compliment each other. Even old Pochman can be sprinkled in and used to handle parity.
