I used my brothers O/H 450g paired with a saltiga Z40 and PE6 earlier in the year up north jigging for reef fish and bottom bashing. Feel the 450 is over kill for the Z40's drag the 350 would be better suited to it but having said that we caught some massive vermin on it, sharks, cod, barracuda, GT's (get killed for saying that here lol) and its a pleasure to use, very easy on the back.
One thing I don't like is the wide range of PE class for it, the 450 rated PE 5-10 and the 350 is PE 3-8, I reckon the 450 is a PE 8 rod and guessing the 350 would be PE 6, they are heavy in the hand compared to my smiths and there's no way you would use them on the lighter PE side. Found them a better bottom bashing rod than a jigger buts that's probably because I'm used to the smiths light weight and crisp feel.
