Hi, booth. Congratulations on your upcoming certification. The water temps at Lake Pleasant have been in the mid to high 60s recently. For diving wet, 7mm would be my choice. You might be able to get away with a 5mm, but make sure to strip it off during your surface interval and allow your core to warm up. The air temps are still running in the 80s here, but the breeze can really make you cold after being in cold water. Make sure you keep us posted on how everything goes. You should also meet us there sometime for some dives. I'm usually at Pleasant at least once a month.
