Hi again guys.

My wiring is done, my frames are built and my pocket is now empty. All this time - I have had a fantasy that somehow I will suspend my pj in mid air to cut out the need for keystoning - thus preserving my hopefully perfect image. Now seeing that my box is well over 900mm long and as heavy as... me - I have decided to go with a split set up (maybe even a vertical set up so my gf will let me keet it behind the couch).

So Q 1. Does this auto keystone/weight on bottom thing really work. Does it work better or worse then other methods?

Q2. What is the differnce between FS, hot and cold mirrors? I can find UK based hot cold guys but no FS guys. (I'm aware the auto keystoning wont work if I go vertical). How much light am I going to loose if I choose to go this way?

Thanks guys (and girls?)
