We are doing so well on rotational effects....lets talk about penetration enhancement in regard to the arrow construction disregarding rotation. 
Now....once again....SMJ brought up a very good point pertaining to one facet of penetration enhancement.
(He is really good at getting my gears going )
As SMJ pointed out, a stiffer shaft is very beneficial for enhanced penetration but this is not a good idea when it effects the spine of the arrow
Some shops and individuals will over spine an arrow to slipshod tuning a bow correctly and as a side effect....penetration may be increased.
I say "may" because the tune has everything to do with penetration losses....as SMJ also pointed out.
If the arrow is used to tune rather than tuning the bow...you are going to lose two fold.
(Huge penetration losses
)
Also, increasing spine while increasing weight can also hamper penetration....reguardless of what so called common knowledge dictates.
(weight gain & penetration gains are real but only in certain instances...not all )

Moving on....
As was mentioned back in '08 (last week) increasing the forward portion of the shaft to allow increased penetration due to frictional losses being reduced based merely on contact reduction for the following portion of shaft after the broadhead/point.
The Alaskan Grizzly Sticks are one way of enacting this effect as well as increasing spine significantly.
Another option is to use an outsert on the forward portion of the shaft.
AFC (defunct) used outsert and penetration was sic with this shaft
The same outsert can either be made by milling or by using a bulldog collar.
The Bulldog collar is a pretty cost effective/weight effective alternative but is not the best of all options due to the minimal increase to the diameter of the arrow.
This collaring can be done with the Speed Pro arrows to effect the same qualities as the Alaskan shaft when speaking of spine enhancement.
These two shaft manufacturers will allow any weight bow to have a spine & forward point advantage over most all other manufactured shafts.
** Right now, I am working on a rig that will employ everything I know on bow/arrow super tuning for the benefit of penetration on a light poundage bow.
We will see what the results are with this one through out the summer/fall of '09.
SO.....can we tackle two issues at once?
