I'm sorry, but I think people put too much into perfect intonation. I have used Telecasters for years, and most of those have been with 3-saddle bridges. I have never received complaints about my intonation nor have I noticed anything wrong myself.
I have 4 T-style guitars. Two have a Wilkinson ashtray bridge with compensated brass saddles. One has a stamped brass bridge with 6 steel saddles. My other Tele has a vintage style ashtray bridge with compensated brass saddles. To my ears, they all are intonated fine.
Again, I'm sorry, I think too much emphasis is placed on perfect intonation. It can't be done; especially if you are playing out. Environment plays a big role. Hot lights, humidity, etc. will play a factor with intonation; no matter wat kind of hardware is being used.
