On the last Public Test Realm version of patch 3.3.3, both these were broken. These problems might have been fixed, but possibly not... [added - renork says not]
- The Weather-Beaten Fishing Hat's lure can only be used on WotLK fishing poles (Kalu'ak, Jeweled, Bone). Other poles result in the error "item level too low". Probably related to the hat now requiring level 70 to wear (twinks were getting it via the Fishing Derby).
- High Test Eternium Fishing Line displays a +2 bonus to fishing skill, even when newly applied. Possibly related to fixing the previous patch's "free" upgrade of +2 glove enchants to +5.
