My only input would be that imagine you have 2 scenarios -
1 - Two trees 19 feet apart and 5 feet around
2 - Two trees 14 feet apart and 1 foot around
In scenario 1, you'd have 10 feet of line tied up just around the trees (so 5 feet per side).
The Superfly has an 11 foot ridgeline so you'd need 8 feet of cord to make up the difference of the 19 foot distance between trees (so 4 feet per side).
Now you tie your prusik on each side (I'm assuming what you are meaning here is something like a taut line hitch at the end of the lines).
That's 9 feet of cord needed per side to accommodate scenario 1.
So let's say you end up with 10 feet of line per side to be on the safe side.
Your usable adjustable length per side is only going to be half that length if you keep the taut line hitch tied always at the end of the line.
Meaning, you only have a minimum usable cord length of 5 feet per side.
Looking then at scenario 2 you have an 11 foot tarp ridgeline so you'd only need 3 feet of line total to make up the difference of the 14 foot distance between trees (1.5 feet per side)
You'd need 2 feet get around the trees (1 foot per side) for a total length needed of only 2.5 feet of line per side.
Your minimum working length of cord per side is 5 feet meaning you'd have to untie your taut line hitch and retie it.
Not a huge issue but something to consider.
A way around this without having to tie and untie knots in the field and without added hardware is to tie a loop of cord out of an additional piece of cordage and string that through the split rings. Then prusik that onto your lines. You have infinite adjustability with this just remember to tie a stopper knot at the end of your tarp line or the prusik can slide right off.
