I have the WB, with no arrow flight problems. Like anything you change, you' ll have to retune your bow!!!

Porpoising usually indicates a nocking point problem. (POI arrow is tilting up it is too high nocking point, arrow tilting down to low nocking point)

Fishtailing is usually caused by one of two things arrow stiffness (spine) or Arrow Rest Adjustment. If spine is ok, your rest may need to be moved to the right to ensure no contact with the disc or ring of the WB. If being diverted down, the rest may need to be raised or tilted depending on the model. Just a guess.

Is it installed correctly (WB)? Did you buy it at a local proshop or can you goto a local shop to help setup? Your owner manual should have a section on tuning your bow, look through that and determine what is happening for sure with arrow flight. You can also find lots of info on the web by typing in Tuning a Bow in any search engine. Most Bow manufacturers have a section on their sites as well.


Oh BTW, I did have 2 buddies who had to adjust their sight pins for POI after tuning and switching to the WB. But you must first fix the flight, before doing any sight adjustments.
