Laser Competition damage

The Laser Comp clearly isn't necessarily an all year round tent. It's good, but not perfect. At the tail end of Storm Desmond and on the edge of it in the Peak District, it was pitched for a weekend in gale force winds for some 36 hours. It survived but the little plastic buckle at the foot of the zip pulled away. The buckle was left intact but one side ripped away from the tent. It wasn't a great problem as I used a tent peg to secure it - this could be done from the outside (when I was leaving the tent unattended) or from the inside (when I was in it). However, it is a weakness, I think, as a friend who also had a Laser Comp suffered exactly the same damage.

Here's a photo of the repair I've done, using a scrap of Dyneema gridstop.
