SilNylon is supposedly 'stronger' than SilPoly, but SilPoly absorbs less water and will not sag.
I just returned my MSR Front Range to REI because the sag was unbelievable. Go to bed with a very taught pitch and wake up three hours later at midnight with a flapping, saggy mess. So yeah, I'd be avoiding SilNylon unless it was for a very lightweight cat cut tarp that probably won't get rained on, or if it had some other structure provided by the frame of a proper tent.
Ah, I read the dimms that said 276cm x 120 and assumed it would be fine.
