>> …just trying to get an idea of what it can handle/how I might need to alter it.
I have one of the original Hex's — not even a Hex "3".
I agree with the other posters. It is great in Winter, though I have never had it out in extreme snow or wind conditions.
A few notes:
1) I clipped off the plastic clips and stock webbing straps that come with the tent and replaced them with long cord and "Figure 9" tensioners. This allows me to loop the cord under a deadman and tie it back off to the tent, even with numb hands inside thick mitts. In fair weather, the long cords also allow an extreme elevated pitch for more room inside and better ventilation.
2) To create a quiet, taut pitch in high wind, be sure to use the additional 5 side edge tieouts. I've pre-tied cords to these to use when needed (without Figure-9's to save weight).
3) A Ski works great instead of the usual pole if you get the length just right. It can be angled somewhat to adjust the height. You may have to build a mound or dig a hole for the ski to get the height you want. I've used my plastic ski boot shell on the end of the ski to prevent the ski from sinking too far into the snow if the snow isn't firm enough for the ski alone.
