Thanks for the feedback
I ended up changing the 5mm spacers to 4mm spacers, replaced the Phil 113mm
BB to a UN50 110mm BB I had laying around, made some front derailleur limit
adjustments and cleaned the drivetrain... Quick ride around and things
seems to be shifting very well.
Haven't had the chain try to dive in between the rings either

I recall a Grant write up a few years ago comparing the Silver to the
XD2 2 and I remember something about spacers on the 74mm BCD posts.
If the crank is on the bike, you can measure the distance form the end
of the seat tube to the teeth of the Middle and Inner rings using paper
cut
to size, and then the difference is the middle to Inner ring spacing and
verify if > 5mm.
For reference, my XD-2 with Sugino Rings have ring spacing > thr 5mm
Shimano standard:
Outer to Middle, 7mm
Middle to Inner, 8mm
