I'd say take 'em in for a tune up and see what the tech says. Keep in mind he may be trying to make a sale, so work the situation accordingly.
Personally I have (company year end bonus, thanks Mike!
) a Browning Rage. We went out that day and I drew back over 20 different bows. The Browning was the one I was the most comfortable with due to its 'smoothness'. It draws sweet and consistant without the dramatic let-off. Also, under $500. Good luck!
