Gus,
 
Alembic has carved asymmetric necks like the Tobias;  I'm sure they could make one for you.

An asymmetrical neck is slightly thinner on the treble side, making it easier to play notes on D/G strings. Wouldn't really need it if the Rogue neck is thin enough, but the Epic 5 could sure do with it!

I play an average of three one hour sets a night with little hand fatigue.It's what I like best about my Rogue 5.The fast neck action and playability.When I first got it,having never owned a 5 before and especially play my thin necked Epic 4 for 10 years,I was a little wary of a fiver neck but after a few minutes of playing her for the first time I knew it was for me.I have fairly little hands too.

When I did my first custom order with Alembic I shipped them an old Tobias Basic of mine with a thin and asymmetrical neck profile I loved and they copied exactly!

Well, it might sound a little weird, but I've changed tack completely and am purchasing that beaut little Zebrawood Excel 4 that David has had here in Sydney for a while. After playing it last week, I just had to have it, the combination of body shape, balance, sound and playability just blew me away! (And it looks hot too!) The FatBoy at the bridge gives a great funky tone with plenty of punch and the mid-placed MXY just balances the sound out nicely. The Pau Ferro fingerboard also keeps plenty of low-mids in there too, gives a nice warm focussed sound. The only thing missing from this particular Excel is the filter and Q switch, but I'm sure those won't be too hard to add in there somewhere.  
 
Just goes to show you can't predict which model will suit you until you try a few out! Now I can't wait to save up more money and order a super-Phat Excel-a-Rogue 5-string! :p
 
Cheers,

Congrats!!
