It's a great bow. I shoot a PSA now, but I’ve had PMA's before, and wouldn't mind having one again someday. BW stock strings are not prestretched, so you will probably continue to see stretch for the next few weeks, so just keep twisting it up and don't worry about it. The weight of the PMA does give one a feeling of being in better control of the bow, but it is just as important to keep a solid bow arm with a PMA as with any other bow. I also have some lighter weight bows, and occasionally I like to return to one of them to give myself a reality check as to how well I’m shooting the bow vs how well the bow is shooting for me.
