Hello thanks for all the help so far! I have been lurking here for a year or so anyway I am making a UQ I am thinking of making mine out of primalift mainly for a cost factor. I do have a few questions. Everything here is geared in favor of down ( for the obvious reasons. ) Anyway I know the formula for figuring out how many OZ of down I would need but how much primalift will I need? The measurements are 48x52 with 4 in baffle. I am trying to get a 10 degree or around there rating. And have no idea how to figure this. on a short UQ will there be that much of a weight penalty for primalift. Also do I still need to sow in baffles or will a simple sow thru design work?
Also the primalift I am looking @ is from OWF and from the way I read there code its the 2in loft or is there a better grade of primalift to use.
Thanks for getting of the ground I know I will get all the advise I can handle here.
