I've only ever used spray for basting - I use 505, mainly because it's the only one I can get, but it has good reviews from other quilters here. I've never had a problem with spray basting, things have not shifted despite lots of 'shoving' the quilt in and out of the sewing machine. If you do a search for 'spray basting' there are lots of threads about it, you may pick up some helpful hints!
