Watched a review regards gong wings.
Mainly positive.In regards to the batten ends.The ends only have a bit of tape to cover the tapered end.
In the review there is a concern that over time the end of the batten may tear or piece the end of the batten pocket.Not proven yet so no dramas.
Heres what I did.
I cut some sticky back soft 3M silicone strips
80mm x 15mm x2-3mmthick from a product called Nowacs.Not available now but had offcuts.
Its only a precautionary measure.
