Well you may laugh at this - but I'm used to it!
My "performance" big board is a 2004 Starboard Free Formula, which I use only with a 10.0. But the waves were pretty big and I was already getting slapped around on the MR 118. So I grabbed my trusty 2000ish Starboard Start, which I still use in certain conditions - like when the waves are much bigger than the wind and I need an 8.5 or 10.0. Believe it or not I will also use that board in gusty offshore winds, it sails great overpowered. Rides like a Cadillac, absorbs huge gusts, and goes through holes amazingly well - probably because it's so heavy!
The board had a reputation as kind of a sleeper way back when, it's from before they added the centerboard. It has a center fin box, but I have a plug in it - and I don't think I'll ever get rid of this board! I have the straps all the way outboard and use a 60 cm formula fin, my top speed on the board (wearing my GPS) is 28 mph! Of course its great for teaching too. So I get over the embarassment and just keep on sailing it and having great sessions, usually on days when I am debating going out at all.
I did see one other sailor out in Evanston later in the afternoon, but not planing - it looked stronger than it was.
Tragically a girl ended up dying last night a couple blocks south of our beach, there were choppers and rescue boats everywhere. The beaches were closed because of the shorebreak, but they went in after the lifeguards left and apparently there was a rip current. Very sad.

Wore a 3/2 wetsuit but booties not needed.
