Tried that! It all caved in last year. We are in a wide open windy field. The best suggestion I got was to use rope and stakes on the cover and run them to the grass and stake it in. Not real sure how that would work!
I have a 33ft AGP which is halfway surrounded with a custom fitted Unilock patio. The patio is snug right under the top ledge of the pool, so it is impossible to get a winter cover and wire underneath it. How can you cover a pool like this?
