RE: How hard is it to switch bows?
As SF said, it depends. IMO it depends more on the person though. I shoot 3 bows alot and even though the SQ2 groups better they all group well. This is the main reason for someone to try different bows before they buy one.
I can drive nails with my SQ2 but cannot with the Hoyt. This can and is, visa/versa for others.
