Jury Rigging will let you repair your sniper rifles with many other weapons, making them much easier and much cheaper for you to repair, as well as being able to repair your armour with almost anything similar.)
(The reason I chose Repair is that at level 14, the Jury Rigging Perk becomes available, which requires you have a repair skill of 90. The remaining 13 points I put on Repair, taking it to 45. From here your skill points are yours to play with, do with them what you will or follow my suggestion. Level 10 (16 Skill Points): 3 points on Science, taking it to 80.Level 9 (15 Skill Points): Put them all on Science, taking it to 77.I put the extra SPECIAL point on Strength to meet the optimal use requirement (Strength 6) for the Gobi Campaign Scout Rifle and most of the other sniper rifles as well. Level 8 (16 Skill Points): Put all points on Science taking it to 62.However, I will still tell you what I chose and why. The perks you choose from here are really up to you, as the rest of this guide does not rely on any one perk being selected.
