I have never found any upside to the accumulator contracts, even without the bend over double up clauses. The math is always 100% in favor of the buyer. Anyone can average a lot cheaper on their own just by selling every day.
A far better approach is to split the 130 bu/ac into the number of trading days before you want it priced and just sell each day the previous weeks low is broken. (For example, you are willing to start selling 100,000 bushels beginning 12/10/2010 for the 2011 crop but want it priced before April 20th. SO, 20 weeks or 100 trading days, 100,000/100= 1,000 per day) If the previous weeks low is not broken, just like in a skins game, those bushels just add to the next days sale. And before you say this won't work, look at its performance over the years. This approach simply destroys the averaging method, which I would point out that most marketing services seldom beat anyway. Its returns are dramatically better than an accumulator.
It is quite common for the buyer to work with you on issues like this. IF you are worried about the double-up quantity, they could easily modify the contract to the increased bushels right now. This way you would then know your net position and you could react accordingly, which might include buying corn to get less sold. Eleminate the unknown makes everyone think clearer.
As to buying puts....you aren't serious are you. If you are, you should wait until the first week of June and then buy in-the-money Sept corn puts. The collapse this year will very likely happen from 6/10 thru 8/15. Options seldom work at market peaks unless you are selling them. Right now with Dec2011 Corn @ 5.80, a 5.50 put is 60 cents. Locking in a 5.50-60= 4.90 floor minus basis isn't really a plan that is working for anyone except the guy in chicago driving his new expedition while writing you the put on his blackberry.
