Fraid you missed the boat with me on this one, I haven't done PP's for quite a while. There are a number of my old PP of the week posts on the forum or listed amongst some of old articles on my Dad's Kempo site here (my PP stuff is at the top of the page):http://www.gosokempo.com/articles.htm
Just some food for thought though, always think multi-dimensionally with all your attacks. One great thing I did get from my PP studies was a better understanding of how to attack the body, getting a better bang for your buck. So you listed the jab in your post. A lot of people actually pay very little attention to where they are landing the jab (or actually how they are throwing it). If you ask them where they are striking to most will say something like, "To the head!" or the really savvy ones might say "To the nose or to the chin". I could spend an entire day just on where and how a jab *could* land. Clipping down on the jaw, hitting along the jawline, the body (and a lead hand shot to the body can devastating despite what many will tell you) and also playing with the angle to access even more targets.
You'll also find that how you set the shot up will determine the outcome. Hitting someone mid-step will yield better results than when they are firmly rooted. Catching them flat footed also cool. As does attacking offline.
Most people take a very static approach to their training, especially many PP practitioners IMO, their training is very dead and lifeless. Your training needs to be alive and animated and most of the targets I hit instinctively now I can only do so because of my timing, distance and structure. In truth with those things in place it does really matter where you hit someone or what with, catch them right, at the right time and they are not going to be happy.
Hope that makes up for a lack of PP!
