As mentioned mate, watch Cotto. Look at the form of his jab, but if you plan to copy, don't load up to the degree that he does. As you're shorter, lessen the power and double it, stepping in as you do so.
:good He's actually remarkably similar to Cotto, both in the way that they throw, and how well they can time an opponent. Intresting to note that they are both Left handed fighters, who fight orthodox.
Yes! I actually had a few thoughts about that a year ago you might be interested at looking at in the context of parallel opponents: http://www.eastsideboxing.com/forum/showthread.php?t=307491
footwork wise Ward's jab is far superior to Cotto's who often over-commits and doesn't place himself out of harm's way.
