You've a green light. You're hereby authorized to fly a Sabre class very heavy fighter equipped with up to four codename weapons listed below. I attach detailed computations for a Sabre class vessel for your convenience. I believe that it is apparent that in every possible way EXCALIBUR class weapons are simply the best option. Each subsequent gun is worse. Additionally, from my own experience, the increased beam speed of CLAYMORE, GOLDEN BLADE and RAGNAROK is not worth the decreased energy efficiency and damage output.
