Doesn’t sound that cheap for just 150yds. Depending what line weight you are after, it may be advantageous to shop on TradeMe. For freshwater a lot are using about 15 to 20lb and as it is so fine they are needing to either buy 300 to 500m spools and one shot it, or wind on a backing line then top shot it at a shorter length. Anything less than 15lb will and does look finer than Mum’s cotton and a real headache if it tangles or if it rubs against your cold fingers….OUCH! Take some bandages with you just in case.
