Thank you for that very intelligent and to the point response describing what should really be obvious to all! It is sort of like selecting the best bat length and weight. The advantage of a light bat is it can be swung faster. A heavier bat delivers more mass at impact. In the case of a bat speed is more important. So if you could increase either length or mass you would choose length. So long as that length does not slow the core speed significantly. There are other considerations with a bat choice but this is just to equate it to pitching. The end of a longer bat is going faster than the end of a MUCH shorter bat even if the core of the person swinging the shorter bat is going faster than the other. So yes the length advantage out performs the core speed advantage. Yes both short and tall have.their advantages. The taller peoples advantages are simply' well... more advantageous!
