I just picked up my first spider a couple weeks ago. They are definitely special I didn't notice any wobbles with my guy, but he missed a non moving target 3 times and took 30 minutes figuring out how to eat it. I've heard they are great eaters and I would have to agree with what I've seen so far. It took him about 10 seconds to attempt the first strike, and the other two were almost instantly after one another. I fed him a few days after I brought him home from the show and he was nuts!

I say go for it! Even if it has wobbles it shouldn't really affect the snake.
