I finally caught the larvitar. It was horrible, days of mistakes and repeat attempts--and with a frame of 2152 that's no fun. I had to change locations because I was getting weird effects, landing on the wrong frame. I was originally in the entrance of Mt. Silver, then I went to the mountainside in grass. I also think, because I did a sleeping snorlax just before this, having the radio on that wake up setting affected the RNG, because I kept getting an onix or an ursaring, and neither are listed on that floor of the mountain, unless I don't understand how they have the mountain mapped out.
Anyhow, I have the larvitar. It's in a nest ball.
