Ive actually thought about getting them myself, but considering I just wanted another one, the cost/benefits arent worth it. Nets/Baits/Gas/Rods/Tolls/beer...adds up. Furthermore, alot of them have fish lice and Ive heard its a pain to get them off.
Lastly, the big ones around 2feet are no problems to get a hold off, while the young ones around 5"-10" tends to be around only around summer time.
