The spinfisher should be fine, just check the drag to make sure it's not sticky. Penn says the drag is only 6.8 kg but I'm sure it's higher also there's videos on YouTube of people landing Queensland grouper on a spinfisher 850.
I'm not sure about the finor as I don't own one but my friend loves his, lands sharks on it. Depends on how old it is though, one of the models (a bit older) has a problem of the handle breaking off.
My pe8 rod is quite still stiff and it is 8 ft. It casts pretty well but 150 m is pushing it. Mabey have you had a look at heavy beach rods?
