Just my $.02 worth. 

See: https://www.tractorsupply.com/tsc/product/weathermaster-lightweight-blue-poly-tarp-15-ft-x-25-ft?cm_vc=-10005 

Considerations:

1. Option to use, if needed. 15' x 25' will easily cover the two existing 10x10s we used at Mile High.

2. Can be easily rigged as a fly cover using line ('ropes' for the land-lubbers) and trees, etc.

3. Much less weight & space to transport.

4. $37.99

Also: I've learned to not buy anything from HFT that has moving parts. (and many other items that have none} See the reviews.
