Which coil is best for direct coil drive wasted spark?

I presently have an EDIS-8 system, but I am investigating direct fire.
I hate the spark plug wire connector towers on the EDIS system, so something like the mitsubishi / dodge coil pack shown here looks nice:

Are there any other good, compact systems? Having four single-coils would take up too much space.
Or I could stay with the EDIS. I hear the Accel coils are nice? Is there a simple way to make custom length plug wires?

Let me put it this way... last time we replaced a well used stock coil with an Accel Super Stock, the car lost 5 horsepower. That MSD coil seems to be a decent one though.

Can I ask what you don't like about the EDIS plug lead connectors? Is it just looks - they work very well indeed.

I would like to do custom length wires, and have more selection. Some of the explorer wires I got are just tooo long in places.
Beyond that they seem OK. I just hate going off the beaten path of standard interfaces.

Here is a Northstar coil pack that I modified to work with an EDIS. The coils use a HEI plug.

It's not difficult to make up your own leads for EDIS. You can buy the coil plugs (and spark plug ones) new - or re-use ones from a scrap yard. That's what I did.
