Depends on a few different things:
1. What's your manifold style? I used an 18" long 1" diameter water heater supply hose stainless braid -- couldn't get a stuck sparge if I tried. When I used the 1/2" diameter 12" long sing supply braid, it clogged all the time.
2. What's your crush look like? If it's flour, then it'll be more likely to get stuck. If the husks are all in tact from the barley portion, then you will have a better filter bed and less likely to stick. You can condition your malt if you mill it yourself (read Malt Conditioning in the wiki)
3. Watch your sparge speed. Slower will be less likely to stick -- especially when setting the grain bed.
I just did a honey wheat with a nice fine dusty/floury crush and no rice hulls today -- 4 lbs pale malt, 5 lbs wheat malt -- and no stuck sparges. If I still had that tiny braid I wouldn't have even bothered trying as the tiny braid ALWAYS got stuck!
