How do they compare as far as speed? I'm stuck between the two and can't decide. I am mostly a racer with limited bashing. I used to own a DX3R and have no complaints but like the look of the 4PL. Is the 4PL as fast in terms of transit speed? It must be fast as I noticed it has a Normal and Fast transit that is designed for digital speed servos. I'm sure I wouldn't notice a difference in speed between the two, but I'm a sucker for specs.
