Orcon is the only tape I have ever had a failure with.
At a Oklahoma CFI chapter meeting the night before a CFI certification, the question was asked if anyone ever had a seam failure. I was told I constructed the seam improperly. I said your full of shit, too. That went over well.
I used CT11SB for years. Then it started to split, right down the middle.
You are dating yourself Mr. Baker. I remember the splitting ct11s orcon tape. Back then I thought Orcon was a joke but they have recovered are are (or were) my tape of choice ....
