E or E/C to match Orig Flex G, D, A

[Ken Smith]

This may have been discussed some time ago and maybe even by me but I am drawing a blank here.

I have some sets with G, D, A Orig Flex and had them matched up with the last of my Stark Flex 92s E/C string that is now basically discontinued. I bought up the remaining stock a few years ago and needed these last few to match up with some other sets so I pulled them out.

Now, I need an E or E/C to match with the Orig Flex GDA. The choices are usually;

1, Orig Flex (too dark for some),

2, Orig Flat Chrome (not a sound or tension match),

3, Flex 92 Stark (when they were available),

4, Permanents (these have worked for me on the E or A&E with Orig's),

5, or a Helicore E or E/C that many orchestra players use (but to my ear they just don't match in tone)

So, I don't know what basses these sets will go on or if it will be a bass that has an Extension but I do need to refresh my memory or the best choices for that set mix. I have done some 2 & 2 with Permanents but for just the E or E/C, I don't recall using anything but a Permanent to mix with the other three that were slightly used anyway.

Your thoughts please?
