When I put the open diff back in the car I LOVED it in comparison. The car was just so free into the corner, rotated nicely. I honestly think that a 1-way might be the way to go as long as you don't mind the car being a little free on corner entry. All you can do is try it and go from there, but I wouldn't reccomend it...

Since you have the parts handy just throw them on and see what you think, and adjust from there.

I had a Tomei 2-way in my miata and now have a kaaz 2-way in my S13. I definitely didn't feel it locking and unlocking in decel during hard driving but it definitely makes the car less versatile in driving styles. In the miata for example, in a tight autocross, if you weren't entering the corners properly committed with the weight on the front it would tend to understeer slightly.

Changing the suspension setup (usually just alignment) to a more oversteer-prone setup will get rid of the majority of understeer. You're supposed to do this anyways when changing something as sensitive to handling as the diff.

I also added Ford friction modifier to my 240 diff which is like twice the size of the miata 1.6 diff lol. I think with fewer discs (or rearranged discs) and some friction modifier that would give you a good compromise.

Despite the shortcomings (noisy during normal driving, requiring more maintenance, ideal for a narrow category of driving) of any performance part, ANY proper LSD will far outperform an open diff in a performance driving environment. A 2 way might not be as good as a 1.5 way for performance driving but it will be far better than an open diff.
