What's your rev matching sequence with the Z?

What's your rev matching sequence with the Z?
Been driving stick for five years, but after learning how rev matching is easier on the transmission, I recently decided to give it a shot. I've been doing it the past week, and found that there 2 ways of doing it.
1 - Clutch in, drop a gear, blip throttle then release clutch
2 - Clutch in, blip throttle, drop a gear then release clutch
I've been trying the 2nd method and I find it really hard because the rpms drop too fast so that I can't get a proper rev match. However, the 1st method seems more logical and easier to me. I tried it today and definitely had an easier time.
My question is what method is "better", or are they both essentially the same thing? Is one easier on the transmission than the other?
I'm on a new transmission (actually bought it) and want to make sure it gets treated properly.

3rd method. Clutch in, neutral, clutch out, rev match, clutch in, pick gear, clutch out. Double clutching and it's what I've found myself doing out of some habit. I need to get the heel toe down, it's been rather elusive to me. Hard to get the amount of brake input I want as well as the gas input.

I do #2, its more fluid. By the time I get around to the downshift the revs happen to be right where they should. Just blip as you shift, should be easy-unless youre granny shifting, which I could understand with a new tranny.
What happened to your old one? I hope this wasnt a question you meant to ask 5 years ago...
If your shoe size is bigger than a toddlers you could try big toe-pinkie toe shifting.

Simple fix for me... grow bigger ***** and brake later! HAHAHA!

2nd choice, kinda. The blip and downshift happens almost simultaneously.
It becomes second nature after a while, and it's meant to speed up the downshifting process. The first method would make things slower.
You'll get used to your target RPM eventualy, and your downshifts will almost be seamless on the road.

While standing on brake, clutch in , hit throttle and select gear , clutch out.
The throttle blip may be a hair before i start working the shifter to select a gear.

You say you like the 2nd option, but I just can't nail it. Whenever I blip the throttle and then shift down, the process is longer compared to the 1st option, and therefore the rpm's just fall too quick for me to get it right. It's actually frustrating that I can't nail it. I usually pick up on things pretty fast.
I just had a feeling that option 1 MIGHT be worse because you're down shifting first without the rev match and therefore the synchros are still working hard compared to option 2 where you're rev matching first and then going down a gear. And I can't do it simultaneously as well, meaning, down shifting and revving. As long as both are equivalent and better than just not rev matching at all, it's fine with me. I bought this transmission new from Z1 and I really to take proper care of it so I want to follow the right method.

2nd method is the way to go. Under normal driving speeds, rev match 500rpm per gear. For example, if you are going from 4th to 3rd blip throttle up by 500rpm. If you go from 5th to 3rd blip throttle by 1000rpm. Just a general speed match for rev matching

Pbn85, while rev matching makes for a smoother driving style, (especially downshifting into a tight corner) it has no effect on the work that the synchros have to do. Once you push the clutch pedal in, the transmission input shaft and all the gears driven by it stop turning. All the throttle blipping and revving you do with the clutch disengaged have no effect on the trans gears. To complete a shift under these conditions it is up to the synchros to match the gear halves speed wise.
If you want to take over the duties of your transmission’s synchronizers refer to EmpireDude’s post on double clutching. A goggle search can explain all the hows and whys.

I do clutch in, neutral, clutch out, blip throttle, clutch in/downshift, clutch out.
I use the synchros less. I'm pretty quick with it. A quick blip is usually at perfect RPM. I know #2 is what you're supposed to do, but I've never needed to do it because I usually brake lightly and earlier, then engine brake when downshifting. Never slowed me down.
I'm more concerned with wear and tear on tranny since I know synchros are poop.
