take the following 2 bows and adjust for draw length of 26.5":

martin scepter using small cam and small mod to change draw length range to
anywhere from 25" to 28"
OR
martin mystic using default fuious cam. it will be set up to a 26.5" draw length (no modifications other than using factory installed furious cams)

MAIN QUESTION:
seeing that the scepter default draw length is from 27" to 32", will there
be a performance hit between the modified scepter and unmodified mystic ?

i post this question because the bow shop i am dealing with has recommended the modification to the scepter. they also sell the mystic but my preference is with the scepter. what would change my mind to the mystic is IF the scepter modification drastically changes the performance of the scepter bow.

thanx in advance...
