From what I heard I think that means they (TAG - who recently bought Kryston out) found a cheaper alternative to sell at the same price lol.... I expect to see 'upgraded' versions of most of their products in the near future.
IMO - yes, a coated braid will help reduce tangles with any bait, not just a pop up (although for resetting a pop up is defo best).
That is quite an extreme measure; Boom is just about the stiffest link available, only suitable for clean bottom IMO. I think a coated braid would be a better option, more forgiving on most substrates.
ESP Tungsten Loaded is the best coated braid I've found, it's not cheap but it's a step above the others on the market IMO.
