The undergarment makes a big difference as the Cap has said. The key is that you will need more, period. Now you have more bubble to deal with where the wetsuit was minimal.
Ideally the 700psi tank weight check would be great but if that was not in your plan keep in mind that if you are underweighted, you likely wont be faced with that realization until the end of your dive when you want to safety stop but your heading to the surface.
**Pinch it, don't stick your finger through. You're just pinching a bigger hole.
