Phil,

Yes.  There are two different styles.

No.  The connectors are not interchangeable.  The connector to
cable interface for the spiral type cable is much more difficult
to seal.  It requires a large adhesive lined heatshrink boot (our
installers refer to this stuff as snotshrink) for sealing.

The connector for the straight corrugated cable is inherently
sealed (with o-rings) if applied correctly.  No heatshrink
needed.

I wouldn't use the spiral corrugated cable unless I was forced
to.

73, Eric  N7CL
