I have the ActionTrax which are essentially the same as Maxtrax. I needed a pair once in the past and didn't have them... haven't needed them since I bought them, go figure. I'm not sure how other brands or colors handle UV, but my black ones are starting to fade to a graphite tie dye look. They have some flex to them and I haven't stripped any teeth off of them (yet). If I were to buy another set, I'd likely go with the Tred Pros or Maxtrax Extremes since both have rubber teeth. The ActionTrax do have a variant with metal teeth, but only at the ends of the ramp. I wish someone made a set that used replaceable golf or track spikes across the entire board. Until then, these replacement spikes
seem like a good idea once the teeth have stripped (or even before).
Since I am currently winch-less, I keep an ARB kinetic strap in my spare wheel storage along with some shackles and a tire plug kit. If I'm planning on hitting more difficult terrain or snow wheeling I bring my winch bag with snatch block, tree strap, and extension/tow strap since you never know how prepared someone else is with their gear.
