I'm sorry -- I think that's a bit of a specious argument: You're comparing a guitar where: 1) different saddles (granted), 2) vastly different bridge size, design, etc., 3) vastly different pickup (P90 vs Tele bridge), 4) Bridge PU mounted to body rather than bridge), Need I go on? That's so many variables, I think it's presumptuous to proclaim that the lack of twang must be attributable to the difference in saddles....
FYI, I have a modern (read MIM standard) tele with a six-saddle bridge and Alnico 3 pickups and that thing twangs like a mutherfucker when I want it to...
Oh yes. I Am sorry. How presumptuous of me to post an answer based on personal observation and experience.
