I have 2 x '05 Zones and a '08 Zone.
All of them have a hole worn in the luff tube where the mast rubs in it when inserting ... about 3/4 of the way up.
I have 6 x '04 Simmers with
no discernable wear, no stitching problems, nowhere near wearing holes in them.
I am sure if you fall on a sail like in a catapault, or run them thru the rinse cycle in a wave, they are all similar strength when new. But it is pretty bad when a sail gets a hole worn in it
just from rigging..... and even worse when 3 model years later the manufacturer has not rectified it!
Even little things like the Simmer bags are still fine, all the zips work, no wear. The NP ones have holes worn in the bag, zips stuffed up long ago and the graphics fell off (who cares really, but still...). All for an average extra cost of $180 each

But I like the vibe and they feel nice to me so what to do??!!!!
