Pulley for Hauling and Rescue - Recommendations?

Hey, I'm in the market for a pulley I could use for both hauling and crevasse rescue. I already have a micro-traxion which I love, but am looking for a basic pulley to accompany it. I'm thinking of getting a Petzl Partner pulley, but am wondering if it'd be worth getting a pulley with a slightly larger sheave or one with a built in swivel. I don't plan to do huge bigwall adventures, maybe 1 or 2 nights at the most, so I'm not sure if getting a larger pulley or a swivel is necessary for me, light and compact seem nice. You guys have any recommendations for affordable pulleys? The SMC CRx is only $17 so Im eyeing that too

Thanks for the info bud, yeah I was wondering why the SMC one was so much cheaper

Camp Tethys Pro ($30) is also quite efficient if you don't mind the extra weight.

Larger pulleys will be more efficient with larger diameter rope. If one plans on using a 2:1 the larger pulleys tend to be pointless as the zed-cord tends to be smaller than normal rope. Focus on ball bearings over bushing for the pulley. For 1-2 night walls, you can generally get by hauling 1:1 with a microtrax so long as you're not going crazy with the bigwall camping load. 

Swivels are important less for the length of the route and more for having multiple bags and/or the traversing nature of the route (and less so the overhanging nature as well); the more the route goes back and forth, the more your pigs will roll and can make getting into the bags near impossible. BUT, this generally matters more with heavy multi-day loads so as long as you're doing fast and light 1-2 days walls, it shouldn't be too hard to muscle the bags back to normal after being twisted. 

Thanks Serge and Kevin. I went with the petzl partner for the ball bearings. I'll get more gear if I ever plan to have a monster bigwall pig
