Angled rod holder for Big E trip

Does anyone use an angled rod holder while on an offshore head boat trip? I'm thinking of buying one for my Big E 52 hr trips. It would hold my bottom fishing Avet 30 w/ SS rod allowing me to jig with another rod while waiting on the "big hit". The angled rod holder would fit inside the boat rail rod holder to give the rod an angle pointed maybe 35 degrees. Cabela's has a "Flush mounted rod holder combo" but the rod holder is made of a hard plastic type material - I couldn't trust it to hold my expensive rigs.

I'm looking for some recommendations based on what others use.

Thanks!
