Looks like the current model went up to $37 and it has 33 tie off points. I got the 10’x12’ in OD Green. Link to the product on Amazon below.
Gold Armour Rainfly Tarp Hammock, 14.7ft/12ft/10ft/8ft Rain Fly Cover, Waterproof Ultralight Ripstop Fabric, Survival Gear Backpacking Camping Tent Accessories (Gray, 12ft x 10ft) https://www.amazon.com/dp/B07C3NKFYV/ref=cm_sw_r_cp_api_glt_i_WFQKQXM5R8RMMAD5T3TW?psc=1
Maybe a tarp like this and a couple tarp poles would do the trick to protect your tent? https://www.amazon.com/Gold-Armour-Hammock-Waterproof-Black/dp/B07C3NKFYV
Something like this? 12'x10', ~1.9 lbs, polyester, $30.
If weight isn't a big deal, there's a lot of similar options on Amazon. Chill gorilla has a 12'x12' at 2.2 lbs, 210D nylon and fairly durable (but also a bit stretchier), $60.
Just a quick tip for trekking pole/guyline pitches, an in-line clove hitch is my preferred way of wrapping guylines around the pole (tip or handle).
