I actually just picked up a Hi-Fi as well last week. It was a 2017 blem model off of evo.com

I started on the Ronix Marsh-Mellow surfboard last year and the skim style board feels completely different. It has a much looser feel and you have to use your rails a lot more. The surfboards are more forgiving and you can ride flatter on them. It took a few times to get the hang of skim style but I like it better. That's just my personal preferences though. See if you can borrow anyone's board before you make a decision or talk to a shop about letting you borrow one. Good luck
