Hopefully one of the screen-savvy members will happen along and give you more concrete advice.

Thx for the replies. Seems I'll be ordering from LMP sooner rather than later.
Hotspotting was a concern. Though the material description is as follows..
High Gain
Reflected images enhanced 1.8 times (gain ratio1: 1.8) within a 45 degree field of view either side of screen centre and never falling below 1 where ever viewed. The gain of 1 applies from 45 degrees right round to the maximum of 90 degrees each side of screen centre (See graph).
Field of view enhancement and no "bright spotting" make the high gain the ideal fabric for home cinema and business applications. However, when viewing from extreme angles the viewer will not benefit from gain ratios above 1.
Fabric is of two-layer construction featuring embossed face sheet and glass-fibre backing guaranteeing strength and stability. The resultant "lay flat" is excellent and reassuringly thick to handle.
Technical specifications:
Weight: 18oz/yd2
Tensile Strength: MD: 47.0 lbs, TD: 49.0 yds
Thickness: 0.21
Tongue Tear: MD: 4,000 grams, TD: 8,000 grams
Fire retardancy: Conforms to US Federal test method 191
Mildew and Fungicide preservation added
Gain: 1.80

Anyone actually got this stuff?
Their top end FP stuff is 3.2 gain!!
All very confusing.
