That's a similar setup as the one I got on my 5.2 with minor differences:

- As it was said before, you don't need the double purchase for the tack line. Just run a line from the tack with a block at the end. Less drag, less hardware.

- I've tried and removed the bungie and blocks which are pulling the slack of the sheet and halyard. I feel I don't need it for the sheet, I simply cross it with the main sheet so they keep each other somewhat in place. And for the halyard tensioner it tends to pull on the retrieval lines, this lead to the line chaffing on the spi, which leads to holes at the bottom of it. Bad.

- I don't have, and do not feel the need for, a bungie between the two sheet blocks. They keep themselves in place without any. (BTW, on mine the blocks further back are harken auto-rachet blocks, the blocks attached to the front beam are simple harken blocks, there is no need to have two ratchet in sequence)

- My mid pole/bag setup with 3 patches on the spi doesn't come back under the tramp, but right in front of the front beam. It is short enough to fit. With two patches you would need a longer bag and a way to get out under the trampoline. I used both a Hobie 16 spi and a F16 spi on my 5.2 (17.5m2 for both). YMMV if you have a larger spi. I use a Stealth bag and ring, they were the cheapest I could find at the time for good quality hardware.
