Great question! That section of Oak is beastmode for downriver SUP for sure. I ride Hala boards because the center fin is retractable and spring loaded, although I still used the smaller 4 inch retractable fin for this run versus the 9 inch. I left off my side fins but now would probably side fin wise just go with the Hala "pocket fins" to add a touch of stability while only having minimal fin (about .5inch) in the river. We just started a FB group called stand up paddleboarding Az... if anyone wants to learn or looking to get out lmk.
