Syncing audio loops on .sgw files?

So I've got the new 9.1 version for iOS on my iPhone and iPad and it's fantastic!
I have a question about keeping audio loops synced together when I send a project file from my iPad to my iPhone. The loops will separate slightly and become out of sync. I typically record in 44.1 kHz, should I initially record at 48 kHz So everything will sync together when transferring back-and-forth?
