Optimizing my Sproing

No... the title is not a euphemism, get your mind out of the gutter.

I completed my Sproing Deluxe last night but had an issue. In previous tremolo builds I've done I had better success using vactrols instead of LDR+LED.

However, my Sproing was a fire breathing overdrive when the trem was on. Barely tamable when the gain was at maybe 5%. Made me wonder if it was intentional. It would make for a very curious pedal (Reverb/Term/OD)
After sleeping on it I wrapped my one remaining LDR and a very old dusty red led in a shrink tube cocoon and replaced the Vactrol.

It sounds really nice now... I got lucky but I have no idea what the specs are on the one I used.

Im planning on building another Sproing and went looking on Tayda and Small bear for LDRs. Who knew there were so MANY types?
My question is (since the build doc is still pending.... hint hint...) what LDR should I be using.
