Im relatively new to blue water fishing and have a few questions about oil rigs. Is there a difference between a stand pipe and an oil rig besides the distance from land? What makes one rig better then another for holding fish given equal water depth? Also, I'll be fishing out of Port A. Are there any certain rigs or rig types that your not allowed to tie to? Thanks for the help. I've learned a lot from this board and hope to put it all to use next week!
