Tarpin system, sliding. Please help

Hello, again. I am sure that this topic was covered before. However, I can not find it where the comparison was made or users stated cons/pros of the ones they have used, and what would they change.
I'm looking to put in the tarp system on my 2003 ravens magnum. I would like to know from those that have one, why they picked what they picked. Why they have picked the one that they have over another. I am leaning towards quick-draw but, that Can change. Please, any information from first hand experience would be appreciated. One more thing, I'm hauling anything that pay. Could be general freight, coils, steel, equipment, insulations... only no O.D. loads. How much are they, tarp system, and what options should I choose? Pictures would be good too. Thanks guys.
