Ok so I have been shooting a whisker biscuit QS for just over 2 years now and I shoot groups with my reflex excursion from 80-60 yards I am in a 6" circle 50-35 Im in a 4" circle and 35 and in im in about a 2" circle, And I do shoot blazer vains which hold up alot better that duravains, or quikspins (which my biscuit eats alive). But I just sold my excursion and im getting a new trykon this week so I will have to post my findings with the bisquit on that bow.
