If I had the speedy 20 first, I probably would not have gotten the MPA. Speedy 20 doesn’t stick out much as it’s smaller (if you are worried about the way the 25 sticks out). MPA will distort its shape if you stuff too much in it (the second pochette literally sticks out if you fill up both pochettes, not so flushed look). Another condition for MPA is the items inside can only store relatively “flat” items as compared to speedy 20, you can store any shape. Also speedy 20 is more reasonably priced when you compare to MPA (in Singapore speedy 20 is $2790 and MPA is $3550!!). That’s more than $700 difference. I find speedy 20 a more comfortable fit for my essentials with some room to spare while for the MPA it’s all filled up, no room to spare. But I love that MPA has a slim profile sometimes and can fit into a bigger bag easier so that I can have a “bag-in-a-bag”. Speedy 20 would take up a lot of space in another bag.
Shortcomings for speedy 20 for many people is it’s strap. Many ppl find it too short, but there’s an adjustable strap version (black only) and I happen to be a shorty so the strap fits me fine. Even if you have to resort to buy an additional strap for speedy 20, it’s not gonna cost $700 right?
Next up is the amount of Vachetta - speedy 20 has more of it than MPA. Don’t know if it’s deal breaker for you. I’m assuming you are referring to get the mono versions for both. Empreinte version would be additional $$$ again. Then in some discussions, many people had misaligned handles, flaws here and there more often for speedy 20 than the MPA. Don’t seem to have much issues for MPA except for the price.
Also I read somewhere in the forum that they heard MPA will be discontinued soon. I’m just helping to consolidated the common discussion points people have about these two.
I hope you manage to get either one (or both if you wish) before the PI.
