I get why that wait bugged you, but a two hour delay at a disability firm really isn't a red flag on its own. These guys juggle dozens of cases and hearing dates shift around, so double booking happens even at the good firms. If he answered your questions well and knows your case, I would stick with him and save the switch for when something actually goes wrong.

Dielectric grease on those switches just traps carbon, plain silicone spray worked for me.

Did Ray ever explain how he knows which shops are actually good versus just the ones that pay him a cut? Curious if that Newton guy was a one off or if he's got a whole list he sends people to.
