Definitely run the Winny all the way through, up to the day...not doing so could cause adverse effects. As for the prop, this can be touchy from guy to guy. A lot of guys would be better off if they ran the prop to the day, because pulling it too soon can make you look flat. Then there are those guys who have excess bloat and water even if minimal they still need to pull the prop. All in all, if your diet and final prep, i.e. water, carbs, diuretics are in check then you should have no problem running the prop to the day of the show.
