Bow poundage wont do a thing for x-tra speed if you remain at 5gr. per. pound.
Krisken,
I do not mean to be argumentative but this is not necessarily a true statement. For example....
...When you increase bow poundage you will have an average gain of approximately 1.75 fps for each pound of draw weight. ...But since you are increasing arrow weight by 50 grains to keep the ratio at 5 grains per pound you also need to subtract approximately 10 fps. ...I did not want to seem like I was lecturing but this is a commonly misunderstood issue.
I, on the other hand, enjoy sounding like I am lecturing.
KE = m*v*v/2 = energy stored in the bow * bow efficiency = S * E
v = square root of ( S * E * 2 / m)
Increasing the poundage increases the stored energy at the same rate as the mass is increased and the velocity is unchanged, if one shoots the same grains per pound.
I.e., Krisken is exactly correct as long as you keep all the efficiencies the same.
