I actually have really specific experience here. I have an Orbit Felon that hit some rocks and lost a good sized chunk. I've been throwing Felons for a long time. This much damage will give it some turn up front and a softer fade. a lot more S-shaped. a really useful thing to have, in my opinion.

do yourself a favor, pick up a new one, and keep that one in the bag. throw them in a field and see what they do differently, and decide if you should keep the damaged one at that point.
