winacts are an excellent limb (carbon) they are superior to any of the other limbs mentioned in the thread so far. Having had countless sets through my hands since their inception i would say that no other limb performs beter than the winnact apart from MAYBE g3, extremes, masters and the winnacts are far cheaper
going rate for a second hand pair is £120 as alt market place will sell you a new pair for around the 150 mark.
