I find that No. 88 by Czech & Speake has both incense & sandalwood very prominently, but I am hesitant to suggest it since IMO it is a rose-geranium fragrance, with incense & sandalwood as supporting notes.
I've gotta agree with mike and hedonist, I think neither Timbuktu nor Fille en Aiguille really conjure up both sandalwood and incense. It's an admittedly difficult combination because they sort of function similarly in my mind. Sure, I can tell the difference because they're two distinct notes, but at the same time, they give off the same vibe, if that makes sense.
Maybe Santal Noble? I guess that's the closest scent I can think of that does justice to both santal and incense. I'm not really a fan of either note.
I have a healthy decant of vintage Santal Noble at home that I have repeatedly sampled. I can't stand it. There is something (the coffee?) that just annoys my nose. I also don't think it's very incense prominent.
Honestly, you probably won't find anything with a substantial or legitimate sandalwood note (Mysore sandalwood, anyway) due to restrictions. For a general woody incense, however, your options are limitless: among many others, I recommend Timbuktu, Dzongkha, and CdG 2 Man.
