E6B vs. Jepp CR-3 "hand propped" Flight Compters.

I am currently using a Jepp CR-3, but I'm working on my Christmas list and
I'm wondering if I should add an E6B.

For high speeds the CR computers have an advantage. They correct for
compressibility, and temperature rise at the OAT probe too.

On the other hand, I think wind problems are easier on an E-6B because
you read GS and WCA directly off the instrument after plotting the
wind dot and setting course. The CR solves for wind in a completely
different way, which saves a lot of space but makes more demands on
the user.

Since you're interested enough to ask, why not go ahead and get an
E-6B? It's not like they're a high cost item.

Or you could buy a military whiz wheel on eBay. I see them there
frequently.
