I don't see anything wrong with that pitch. Silnylon will stretch and usually need to retension my lines 30 minutes to an hour after pitching. You can add pull outs in the middle halfway between the bottom and ridge to pull the sides out and add more room inside and stability to the sides. It may also add some diagonal wrinkles when you use them- mine does.
