I am trying to clean up Cait so she will fall in love with me
and the assultrons guarding Vault 95 are kicking my butt! I have a high powered sniper rifle and even when I sneak up on the ledge, toss grenades and get 2x sneak attacks, those darn robots come and rip my face off. I have a stealth boy but I want to save it till I really need it. I love how tough this game is and I can't wait to go back through it again as the biggest jerk possible stealing from everyone and killing every living thing i come across. 
You should be close to one of your settlements and can lure it into the settlement's defense guns. Defense lasers help out quite a bit. Also, if you have some frag land mines you can sneak to the ramps and place the mines there, then move back a distance and with your sniper rifle make it rain lead.
Good luck with Cait. Casanova err I mean Zuhl is the expert when romancing the FO 4 ladies. Right or wrong he'll steer you in a direction. LOL
