Does anyone still use these bivvys?

I have used mine for 6+ years now (mk3 model) and something about it bothers me and am wondering if others have the same issue. I have a slight leak when it pisses down from the top of the 1st rib, luckily which is in the porch area, and Im sure its because of a dip in the fabric from where the top porch tension pole meets the 2nd rib from the porch. its enough of a dip to hold water.

maybe Im pegging it down wrong?

I peg the first point back first, then the door and the rest of the front, following the rest of the back

Maybe Its time for a new bivvy
