You'd lose that bet. The Lear 35 boards stay out so long as they're manually deployed. They'll blow down if they're high enough,but failure to retract them with the flaps deployed, such as a balked landing once the wheels are on the ground could be problematic; you can't have both boards and flaps out on that aircraft, and there's nothing automatic about them.
Perhaps you're confusing the issues of coming out of reverse with stowing spoilers.
