You may already know this, but they are "Noiseless" because they are actually a stacked-humbucker pickup design. Which is why a lot of people don't like the Noiseless pickups. I actually like them quite a bit.
I suspected as such from their physical appearance. They're very tall...especially the neck pickup. But on their own I don't hear a difference from regular single coils, in terms of tone. In my opinion its the width of the pickup (and therefore the magnetic field, I suppose) that is important for the tone. i.e. a wider pickup, such as the P90s on my Les Paul, 'see' a wider part of the string and thus a different range of harmonics. The neck pickup on a Tele has to be at least a third of the width of a P90. More-so a dual coil humbucker.
I like these pickups a lot too.
I like the S1 switching and the 4 position as well. Not a fan of the noiseless, but you are correct about the smaller magnetic field somewhat. Noiseless pups will not quack as well in out of phase position. There are tradeoffs and not just the magnetic filed. Noiseless pups are great when using distortion as the microphonic feedback is almost none. Really is there was no difference in tone single coils would no longer exist.
It is very possible to properly shield the cavity and not have single coil hum unless something gets close to the front of the pups.
It looks like you have your tele setup to Rock and the noiseless pups are just right. From your blog it looks as this may be the case.
Question: Why is the finish missing under the bridge?
