Any split ring that's strong enough to withstand heavy fishing for a couple of years without corroding is a good one in my book. I don't mind swapping them out but some are less reliable than others. It seems to come down to the quality of the metal and finish. I know from experience that not everything marked stainless steel is of equal quality. Not sure about the zinc ones, but assume it's the same way. It may not matter that much for smaller baits and fish, but musky class baits are where I want max durability. I really like Spro stainless rings but usually pick up packs of them at the local big box stores where available, and they are really expensive in those places. Just wanted some opinions on comparable quality with other brands and sites to buy in bulk. Thank you guys for the opinions and recommendations.
