I cant even tie the front strap on my seat because of tank. I only use rear strap and that doesn't prevent the cushion to flip back with the wind if ever I stand up for a second, so I would love to hear more attachment solutions...
For the rear strap, I dont stretch the elastic much (as I said, it just a safety attachment now), so when not stretched, it still dangles out. Honestly, this doesn't have to resit a hurricane. Besides, I hate so much those square unsecure clippy things that I have to twist to ensure they wont slide off that that I am about to make my own wire with hooks (a tiny bungee cord likely) as a permanent addition to the underseat..
