Pash, my ship has already sailed....
I've bought the upside-down S1 forks with Maxton internals (ex Teambegger) from Ash so will be using them. I'm also running twin 340mm Galfer Wavy rotors and two 6-pot Nissins at the front (er, yes, I like to brake a bit late!) so don't need any more stopping power.
But everything you say makes perfect sense - I really must remember to think before maneuvering.
As for the extra weight daywalker, Yep, that's true. But having loaded up the unsprung weight of the front end (2 Wavys added 1.1kg over a single Buell disc; caliper another 0.96kg; with bracket/brake pads/etc the additional weight is 2.721kg) I'm keen to reduce it again. The front Dymag is 3.5lb/1.59kg lighter than the stock Marchesini - so the front end would only be 1.131kg heavier than it started. As for the "thug" yokes, you're right, only an idiot would fit them.
Just out of interest, the twin disc front-end is stunning! I fitted/made it a few years back and had to adjust my riding style to compensate - two-finger braking is a bit much and if you were to ever grab a handful it'd spit you off the front.
I'm running standard Buell pads - after trying many others these gave the best results (N.B. Such big discs when doubled then used in non-race conditions hardly ever get warm - hence the unexpected pad choice).
