proper punching form for maximum power and speed

I decided to start a blog to talk about punching form to me it's not about style v style,but there are much better ways of delivering maximum power and speed in a punch than others.I've taken good points from both karate and boxing,k1 and even traditional arts, but i don't agree that any style is better than the other it really comes down to the individual and the time you put in,the best style for you can only really be found by many hours of training

Here's some examples of what IMO is very good punching form,Dennis is the hardest bare knuckle puncher I've ever seen,and Manny has top boxing technique.

Dennis Jones

Manny Pacquiao

One is koshinkai /doorman, one is a boxer there both using solid kinetic chain,good wrist position and the right part of the knuckles landing to maximise effect,they've both had many years experience perfecting what there doing in there own field of expertise.they both use forms of focused striking,trained in different ways.
as a side note,the style of punching Dennis learnt in karate was different to the freestyle/unrestricted method he used on the street.
