i finally did it...
to cut the cost i had some "fixed" option (every model is neckthrough):
1) a gorgeous trans-red maple with walnut wings, brazilian rosewood fretboard and fender style fixed bridge

2) an awesome satin black maple + mahogany, ebony fretboard, schaller bridge and EMGs (so a pain in the butt to swap with passives - aka BKPs!)

3) a natural satin maple + mahogany + pao ferro fretboard with schaller and passives

4) a natural satin wenge + swamp ash + ebony fretboard with schaller and passives

i was almost convinced to buy the maple/mahogany natural and have the headstock painted darker (i hate maple headstocks!), but was very curious about the wenge one (and i love how wenge looks, by the way!), so i tried ALMOST extensively both of them and i discovered a couple of things...
acoustically the wenge/ash sounds a bit duller and a lot middier, almost mahogany-like but with more high mids. the maple/mahogany was abit brighter and more scooped but seemed to have more punch.
think about nailbomb and cold sweat bridge... the acoustic equivalent.
played clean through a tube fender both sounded awesome, and retained very much of their acoustic character (both guitars were equipped with duncans... JB in bridge and jazz in neck, not a bad combination). i liked more the wenge, full of hi-mids...
then i tested them in hi-gain situations, or at least it was my intention... unfortunately neither me and my luthier were able to make the mesa stiletto used for the test sound much more heavier than a marshall plexi (voice is very similar!), and quite strangely the wenge sounded harsher and brighter than the maple.
anyway i'll put a set of miracle men, and wenge gave me the instinctive impression to be the "right" guitar for them...
so i chose it! my luthier will paint the wings in darker colour (between mahogany and the worn brown usually found on SGs) because i don't like clear woods...
but as you may have come to know i'm completely insane, and i think i'll buy ANOTHER guitar, this time made of maple/mahogany in the not so distant future...
