This topic has come up on forums over here in the UK and the same opinions came up. I think that I must be very lucky with my technique because I've never had a problem with using re-positionable spray glue on my patterns. I sand the wood with 120 grit then spray the back of the pattern with the glue, give the wood a wipe down with a cloth, stick the pattern down. If it's thick wood or I think it'll burn the cutting then I'll apply clear packing tape after drilling the holes then poke the holes with a bradawl. After cutting, the pattern just comes off, then a quick sand with 240 grit and then finish, usually with Danish Oil. I have found that using 100gsm instead of the run of the mill 80gsm paper also helps.
