I actually used a 68" pilot parachute I liberated from my shop (legally of course!). I like drifting reeaaalllyyy slow and it does a great job. However, it is a pure SOB when it comes to stowing it wet. I am now entertaining a 29" weighted model at BassPro. Comes with it's own storage bag!
My drift conditions usually center on the current. When the wind is up, however, it works great in keeping the bow pointed towards the seas. :D
