I have a -2 Laeger with skid plate mounts being that short you can't put a PRM full skid plate on, but I do have a one fo the shorter AC/Moose/Pro Tech style on mine and have yet to cause any tab damage or any damage to the swinger by bottoming or any other hooligan antics.
I have heard good reports on Eyeball as well as Lonestar,Roll.
I just purchased a set of +2 +1 arms from JD Performance (John used to work for Mark Laeger, he build ALL of Laeger frames) I would also check out his quad tube swing arms. John does great work and his customer service is IMHO 2nd to none
I have personaly seen MANY Fireball (*****see foot note) manufactured swing arms cracked/broken around the pivot, but in fairness to FB......most bikes were ridden very hard and a few were Moto'd
****Duncan, Janssen, ASR and quite a few others that slip my foggy memory
