505 is the best. It is more expensive than the others, however. It does not gum up the needle, not hardly anyway. It is one of the one's that the overspray can be cleaned up. Some of the sprays are really hard to get up. 505 does not smell as bad as the others. I prefer to go to the church and push tables together so that I don't have to get down on my knees. When at home I use old painting sheets around the edges to keep overspray from getting on my floors or carpet.
Spray basting is the only way I bast a quilt any more.
