People using the Hooker mounts are you using OEM rubber or poly clam shell mounts?

Wanted to find out what people that have done the LS swaps using Hooker mounts, are using for the clam shell motor mounts? Are you using the stock rubber OEM type mounts or are you using the polyurethane? I know in the past people started getting away from the stock rubber as they didn't hold up for long, but I'm not sure if these clam shell style mounts are better? I've heard to try and use rubber for the trans mount to help alleviate vibration, but wasn't sure about the motor mounts. I am using solid body mounts for the subframe.

thanks, Jake
