Fretting

A little clicking and I found a post on fdp.com that says:

Here's the info I got from Fender when I asked.
Fender medium jumbo/standard fret wire:
The Fender Medium Jumbo wire is .046" x .103"

So now it's clear that this is what is on the stowaway. Also, looking at the fret size information at Warmoth, I see that this is the same as the Dunlop 6150 size. From the Warmoth site:

Item Number	Width X Height	Description	Used By
6230	.080" X .043"	This is the smallest fret wire.	Vintage Fender necks.
6130	.106" X .036"	Often referred to as "Medium Jumbo".	Many Gibson necks.
6150	.103" X .046"	A true "Jumbo". It is about the same width as the 6130 but a bit taller.	Modern Fender American necks.
6105	.096" X .047"	Narrow and tall.	A popular choice.
6100	.112" X .055"	Huge! This is big stuff for the almost scalloped feel.	Common on Ibanez necks.

This makes me feel a bit better, as it's clearly a respectable fret size.  The neck width is another story.  Now what's troubling is that none of the Allparts necks use this size. Here's a table I distilled from looking at around 20 strat necks on their site.  Note that there's some inconsistency, in which the same name is used for different wires. I sent them a note about this - no response.  Based on this, I wouldn't feel comfortable ordering something from them, as I'd have no idea what I'd really be getting.

Name	Size
Jumbo	.118" x .055"
Jumbo Modern	.114" x .055"
Jumbo Stainless	.098" x .047"
Jumbo Stainless(!)	.110" x .055"
Tall	.095" x .055"
Vintage	.079" x .043"
