Juki 1541s feed dog and walking foot

[Scifidelity]

Hello. I have a new Juki 1541s. I am planning to buy the aftermarket smooth feed dog that Goldstar sewing makes for that machine. I am also considering buying a smooth bottomed narrow walking foot and/ or left side zipper walking foot. My question is first, does anyone have experience with those items that can recommend them? Second, will have a smooth feed dog and smooth walking foot lead to feed issues? Should I continue to use the gripped bottom walking foot? Thanks in advance.
