I have an SL-5, great tent. I thought I'd like the GoLite poncho as a solo, fair weather shelter but ended up with an SMD Gatewood Cape as a similar poncho/shelter that's much better as a shelter.
My father wanted to try an "ultralight" backpack and ordered a GoLite Jam 50 and an REI Flash 45 at the same time. Side by side comparison, the REI flash 45 is way better, much better support as it actually has a frame and the Jam only weighed 2 oz less. The Jam got returned. Neither of these bags are a big game hunting pack though, that's for sure.
The Golite Bitterroot down jacket has quite the following as one of the best down jackets available for its great down weight/total weight ratio and $200 price tag. They aren't often available online. Can't comment on durability as I've never been lucky enough to snag one but durability issues come with the territory with these ultralight companies, always a compromise between weight and durability and some push that envelope too far.
