The tapes held on mine. I think on Todd's they tore.
My hole started small, so small that I didn't notice it until I saw a weird reflection on the jib coming from behind the spin (which should have been blocking the wind) Over time it got bigger and bigger until it stretched across the whole mid-horizontal seem and down to the middle snuffer patch.
Two days later, during a double trap spin reach, the head grommet pulled out of the chute.
Reinforcing the grommets has been standard fare for us for several years - this is the first time I've had a seam come apart...but at least most of the entire fleet had the same issues. We'll add stitching the seams to our prep list in the future.
I don't necessarily think it was the tight reaching - sure, that puts some extra stress on the sail but ours let go on the day we were running deep in 12 to 16 knots of breeze after already holding up for 50 miles or more on the same angle of sail.
It sounds like EP will graciously take care of the problems - it sucks that several of us had the issues we did but it's not much different than in NASCAR when they get a bad tire compound with their supplied tires that results in a lot of flat right front tires. That's racing.
