well the extra length in the bar will make it easier to get the salt into, mind you it will sting like a b!tch. As long as you keep the piercing clean it should be fine. If you are ever worried about a piercing and your not happy with the first responce you get, always get a second opinion.
If the extra length doesnt help then mabe you should look into getting a PTFE retainer, just whilst its healing.
I'm having to think about that myself at the moment. I want to get a scaffold piercing in my left ear so I'm looking into it. I've heard that its a really hard one to get to heal so I'm thinking PTFE is the best way to go.
