Yeah I wish I had the patience to do that

I use Monte Allum's set on the SD1 with a couple of my own changes and it's just fine for me. One day though I'll build a simplified TS as a test bench with socketed opamps, gain resistors and signal path caps/resistors until I get it just right. It's expensive though
Anyway the opamp and clipping diodes are, as has been suggested, the first thing I change in a TS style pedal. The TL072 is my favorite though I only tried the 4558D, DD and P (all junk to me, though the P was slightly better. Keep in mind the difference a single different opamp isn't HUGE, but it's there). I also use 1N4001s, or 2s depending on what I have. Same things.
I also use SD1s, not TS pedals. Way cheaper and the circuit is pretty much there already so why not.
Anyway out of these the diode choices and the opamps are the only things I chose myself after trial and error. But it was worth it. Oh on my latest SD1 I kept the assymetrical clipping and used a random GE diode
The biggest tone difference I do is a blue LED. That gives it all its coolness muahah.
(just joking)
Either way it's honestly not THAT hard if you understand very basic electronics to figure out which elements make a difference. Simply identify the signal path on the schematics. It does take a bit of learning and reading around though.
