I wore an SOP for years, but needed to get a new harness and tried them all out at the sporting goods stores last winter. I had really thought that I would end up with the tree spider or muddy, after hearing so many good comments about them, but didn't. I didn't like the way the tree spider fit and the fact that there is no waist belt. The muddy was very cheaply made in my opinion and I didn't like their leg straps (cheap pull though) or waist buckle (no real buckle just a rectangle that you fit though another rectangle). The gorilla G-30 was nice, but smelled really strong and nothing that made it stand out as better. I ended up with a HSS pro series and was so impressed with it, bought another for my daughter, to upgrade hers as well. Hers is the lady pro has the pink trim. The are heavier than the other brands, but so much better thought out and constructed in my opinion. Nice buckles and straps, lots of extras and accessories available. I see this year there is a new one the is kinda a combination of their pro series and ultra lite called the Hybrid. I would really look closely at one of those.
