Men's MM Jailbird Spike Options for Punishment

Do any owners of the Jailbird have first-hand knowledge regarding the “punishment” or “anti-pullout” pins? If you do, could you share some details? (Feel free to send them privately.) The device comes in three sizes and three styles — making nine total options. How does each one feel? (You are allowed to choose three for your order. I’m leaning toward picking one of each size, but the style choice is still up in the air.) Do they cause pain continuously or only during moments of… misbehavior? I realize I’ll need to return my device to get this modification done. It has to go back regardless because the gap was originally too wide, and now it’s become too narrow — resulting in ball burn! I haven’t documented this yet in my journal, but adding these pins is, well, necessary.:oops: Any guidance would be welcome.
