I actually assume that I am gonna pull-a-philly™ on these PUs.
On one hand none of my current axes got empty space and on the other none of them really would befit a pickup of this gravitude.
So I shall for now pay tribute to the curator of parts of the ages and meanwhile start thinking about what I want my first custom axe to be. Then I gotta see how the first year of uni does affect my money and maybe if I am lucky get a first payment down on a Feline Custom I can put these beautis in.
I actually have been thinking mostly about what PUs I want in my first custom and then these come along and seem perfect as I really was between the Stormy, Blue note and the PG Blues.
Now I am thinking these in some sort of a Fender scale Les Paul with 24 frets, but sides that rather classic design should be really swell...so many things to think about and research =)
Shall I just hang on to them till you are ready for a guitar to be built around them 
Could actually almost do that, but I wanne enjoy that new pickup smell and look at them from time to time to keep me inspired to plan the guitar and practise playing so I can justify actually getting a custom ;)
Use them as somewhat of a carrot on a stick kinda thing.
I would guess realisticly the earliest possible time to put down a payment and get things going would be like 9-10 months from now. Really gotta see how my bank acount shapes out first. Should give me time to plan and practice so all is good.
Will take me a lot of time alone to figure out the neck I want. And when I am done planning I might even think about flying out to London for a weekend to drop by and get the final order in, looking at some of your suggestions to see how they would fit me and stuff....all in the future.
I also really wonder how many of these PUs will fall into the hands of forum members here.
