SPD-SL versus SPD stack height?

I've just upgraded my pedals from PD-M540
SPD's and Nike shoes to the PD-R600 SPD-SL
pedals and SH-R151 carbon-sole shoes.

I'm wondering if I should adjust my saddle height
and if so by how much? I can't find stack height
figures for either. What should I be looking for?

cheers!

I could be wrong, but I thought that most people adjusted their saddle
height by experience and feel. If it feels too high, lower it. If it
feels too low, raise it. That's how I do it. Most people who have never
seen any instructions about what is considered correct saddle height
will put their saddle far too low. But if you follow some instructions
too literally, you may end up with it too high. I believe that one thing
that is important to remember is that it is a saddle, not a seat. Your
feet should be supporting a fair amount of the weight most of the time
to give you better control of the bike and some shock absorbing. This
isn't possible if the saddle is too high or too low.

Upgrading from shimano spd (should be pd-7410) to spd-sl (pd-7750)
keeping the same shoes I lowered a bit my saddle (some 2mm) and it feels
like before.
Not sure I can really feel 2mm of difference, but it seems ok.

I can't answer the original question either.

The easy answer it to just install the cleats/pedals and go ride and see. Just
ensure it's not a long, long, long first ride. The more involved answer is have
somebody do a cleat/bike fit to see measuring leg angle, cleat position, kops,
etc.

New shoes, new type pedals/cleats involve a lot more than just stack height. it
also involves where the cleat is, fore-aft and left-right.

I realise this, but I thought there might be an easy "add 2mm
for that shoe/pedal combo" that would ensure my saddle height
was pretty close to original.
I did my commute on it yesterday (26k x 2) and it feels pretty
close, height-wise, but I still have to adjust the cleat angle for
a little toe-in.

thanks

Here's a list with distance spindle center to bottom shoe:
Campagnolo - 20mm
Look - 22mm
Miche - 20mm
Ritchey - 12mm
Shimano SPD - 16mm
Shimano SPD-R Ultegra & 105 - 14mm
Shimano SPD-R Dura Ace - 12mm
Shimano SPD-SL Ultegra - 16mm
Shimano SPD-SL Dura Ace - 14mm
Speedplay - 13mm
Time Equipe Pro - 12mm
Time Impact - 11mm

Looks like you don't have to change anything for the change in pedals.
Only difference could come from the shoes.
