Hello, I am looking at Blue Jeans Cable for speaker wires and they offer 6.3 mm, 7mm and 9.2 mm spades. I saw an old thread here where Dave answered a question from someone that said their 6.5mm spades didn't fit and he recommended 8mm. BJC doesn't have an 8mm option from what I see.

Has anyone used 7mm spades from BJC for Ascend Acoustic speakers? Will 7mm spades fit better than 9.2 for Sierra LX and a horizon center? BJC website makes it sound like 7mm should fit most speakers and that it's better to have the smallest fitting spade for the post.
Thanks for any help!
