Integy...

[Sower]

I've always heard it pronounced like the G in gym. As for the other questions, I'm not sure on all of them but I can comment on my experience with their quality.

I had some CVD's of theirs on my Mini-LST and they were horrible. Broke two of them in about two weeks. Stock drive shafts had lasted me months. I've also seen a lot of their aluminum parts bend easily. Maybe they've improved, but I won't buy anything from them. That's also due to no customer service when I mailed back their broken CVD's. No reply at all. I'm no fan of InteGy's.
