Austin,
If you want to get 'half-way' shutter speeds, that is: exactly half way between say 1/60 and 1/125, it won't really be helpful to set the camera on Av!
Check out the owner's manual: in Av-exposure you'll only get what the Manual calls a suitable shutter speed, designated "1/90" in the viewfinder – which in reality could mean anything: 1/82 or 1/102 or whichever speed is suitable for the situation you're working in, in correspondance with the aperture you've selected: this will always be an approximate shutter speed somewhere inbetween two standard shutter speed-values, but rarely a shutter speed exactly 1/2 EV faster than 1/60 (nor exactly 1/2 EV longer than 1/125).
Shooting with slide film it can be useful to get exact in-between-speed. I believe, the only correct way to go abot it is:
Set the camera to Manual exposure mode. Dial in the the shutter speed that you want to get faster by 1/2 EV; so if you want to get 1/90, set 1/60.
Next set the ABC-lever (provided you've activated Custom Function # 2 – 1) to +/- 1/2 EV: the viewfinder-LCD shows 1/90.
Then: Expose the frame; and immediately reset the ABC-lever to "0".
Result: you'll get an exposure exactly 1/2 EV shorter than 1/60 (i.e. 1/2 EV longer than 1/125)!
This procedure isn't elaborated upon in your Aria-Manual, but you'll find it briefly mentioned on p. 138.
Good luck, Peter (the Netherlands)
