Should I go for a shorter leash?

Last week I had a pretty close call. After being really sick for a whole month without any exercise. I went out when it was a few feet above overhead. I saw at least 3 regulars came up limping as they have injured themselves. It was big, but I did catch some awesome waves. However one of the bigger set came in and probably look like 8-9 feet. I was in the wrong spot and behind me was the boil/reef. Got held under by 3 waves. I couldn't resurface, although I wasn't really deep in the water. I'm close to the surface but something was pulling me under. I ran out of air but managed to resurface and I drank some sea water.
I have a 9'0 board and a 9'0 leash. I'm thinking since I'm not going to go all the way to the nose, I should possibly get a 7'0 leash so if I loose the board, it will at least be closer to me. I already took out an older lady last month when I did a failed turtle roll and the board flew out of my hands and smacked her.
