If money is not an issue, buy a 55g AND a Silent (which only comes in variable weight). Then open both up, unscrew the plate with switches from the PCB and swap the silent plate over the 55g domes.
That's what I did, and that's the best Realforce experience I've had so far. Silent sliders make the 55g feel a little bit lighter, probably between 45g and stock 55g, but that might be subjective.
You might want to do the same, but seap silent onto 45g instead of 55g, though, if you are worried about the weight. Also, the same can be achieved using topre silencing rings from Hypersphere, but more work and you will have to wait for a groyp buy or be lucky to find them somewhere to purchase.
EDIT:
Also, I still think the best Topre experience in general is HHKB, but I can't live without F keys, arrow cluster, and home/end. If you can, go for it.
Also, also, typing on a phone sucks, look at all those typos above lol
