I don't think it sounds... weird... (Well, I'm thinking of, like, the first 15 episodes), but I do feel the boy voice is somewhat forced there. I still like how it sounded in the 20s and 30s, and I guess 40s of the original series- I'm too lazy to check. That's when I preferred it the most. That's probably why when the voice switch from 4Kids to TPCI was expected to happen, years later, I wasn't initially upset that Ash was getting a new person to voice him.
