daz i know you wont do this but it would be interesting if your custies were given envelopes and a pole slip inside rating your wfp against your traditional cleaning, you know to see what they really think without having to say it to your face, i still doubt that wfp can do a better job than traditional cleaning and i think your custies would tell you as much given this kind of vote, i think im right in saying you cleaned frames as well before going wfp. that said im am pleased its going well for you.
