Just a few comments.
I've got the 41, and use it a lot. It's about the same heft as a SwissChamp: the bitkit fits in the space of the magnifier and philips head.
I've found the metal saw to be useful in cutting through bolt heads, and the wood saw to take out a three inch tree limb. The bits are just the right size for electronics, but the largest philips head is a bit too small for real high-torque situations. Interesting comment on the empty holder; it's just the size to fit the bolt heads on a Kershaw ET. The pliers are useful when you can't get a good finger grip on small fasteners, Not a lot of leverage, but I've not been too gentle with them.
By default, the 41 has turned into my beater SAK.
I do agree it's bulky (it's pouched), and I carry a 34 when bulk is an issue.
