Foam would be best for his safety for sure.
The board has seen its days and dinged up but water tight so it has hardly any monetary value (though a good floating value!); hence the "long-term" loan offer. It's not shiny white so he might not like it, actually. ha
Good luck with the foamie hunting!
Feel free to contact me if you are struggling, I'll keep my eyes out for foamies too.
