Wading through the endless list of instalment warrants

How on earth do people choose an installment warrant out of the long list?

For instance I'm looking at Woodside Petroleum (WPL) and there's dozens of self funding/installment/mini all with different expiry dates strike prices and so on. Is there a table or calculator or something to compare the different products? I assume different providers price their products cheaper/dearer.
