I second this statement. LT150 is too dim for gray screens unless you have small (<80" wide) image. Behr Ultra White should have more gain than blackout cloth but the contrast may suffer too. Neutral gain screen is most versatile. I'm curious about the Parkland Plastic stuff though. My local HD/Lowes do NOT carry these. 48" is not high enough for 96" wide screen (needs 54" for 16:9 screen which is perfect size for blackout cloth). I'm too cheap to buy $40+S/H for 5'X10' sheet.
