I've been offered a lightly used Golite Hex, it's not somthing I've seen or heard about before. The size, particulaly height, and simplicity appeal to me. I've read a few reviews on the web, a bit mixed but mostly positive. Anyone got any experience of this or anything similar? What's being offered is just the shelter, no inner tent, you can buy these but I'm tempted to make my own. Maybe just for half of it, leaving the rest as a porch and keeping the weight down. A couple of people have reccomended I try a cotton inner, any thoughts? Lastly, any idea what I could use for groundsheet material and where I could get it? Would proofed ripstop be alright? I'm OK with stitching it together, but how would I seal the joins? Would normal seam sealer stand up to the abuse? Thanks.
