Have had Hunters and Hatfields some years ago (two each), both models were decent shooters and fairly fast bows but in my case they were prone to limb twist even though treated and stored carefully (used bow stringer, stored horizontal on pegs, avoided heat, etc. etc.). "Bumping' the limb worked for awhile but eventually the twisting persisted. The company was not at all accomodating regarding the problem, though only one of the bows was purchased new.
That was 15-20 years ago. A friend's neighbor recently had a new Martin X-200 recurve...a bit less expensive model than the Hunter...delam on him. I never had that kind of issue with mine but one has to wonder about the current quality.
I don't mean to dice on Martins, when in good shape they are very good shooters. But despite owning many other bows over the years I've never had that kind of recurring problem again. Decent bows yes...but you might want to check your limb alignment every so often just in case.
