I have an opportunity to buy a Diawa zillion sv tw for $180 brand new. The thing is is that it is the previous model the 2016 not the 2021 newest model. I am wondering if getting the older model is still a good buy compared to the newer model. If you have owned both and could give your opinion even better. I have been between the newest tatula sv tw and the zillion sv tw but seeing this older model for the price of a new tatula just not sure what direction to go in. Thanks for any advice.
