I was skilling up making the NQ version of these (Fisherman's Hose) and even though I am 22 Clothcraft (1 level below the recipe) I synthed the +1 version - Angler's Hose. Making +1's on skillup recipes is pretty rare but I have seen it happen when skilling up in Goldsmithing before. However, i'll bet +1's are frequent by nature for this recipe since the +1 version of this only has a higher lvl requirement and a 'lil more def (rather than adding more to the vital stat + fishing)
