I think a bit of a wobble isn't a problem in itself, but I can understand why it would frustrate you when paired with a slightly shy/nervous disposition in your BP. Our spider has a moderate wobble when she feeds (doesn't prevent her from being an absolute pig) but in general she's an incredibly chilled out snake, who doesn't seem at all stressed by frequent handling. If her wobble was getting worse from interacting with her, I'd probably try to sell her as well as I like to handle my snakes. Everyday does sound pretty frequent though. We usually give ours the day before a feed with no handling, day of the feed no handling and day after no handling, so they're handled about 4 days a week, which many on here would still consider pretty frequent.
