Just remember, more cutting = more friction.
Yep... Go with big cutting heads you best have enough Umpphh to push it through...
Yup, and too many think bow poundage the only determiner of "oomph".
Power stroke, bow design, momentum, quality of arrow flight, FOC (minimized deflection under load).
Most folks only know KE to a basic level (but hey it sells bows in the shops).
And they seem to think larger cut = nothing but positive benefits.
Aint nothing for free.
