My $.02, stock plate all the way. Unless you want to carve a bit more where the shred master or JD helps.
JD pushes the nose down and hooks hard, kinda makes it hard to slide. Needs a lot of steering input to turn. Less porpoising when pinning it.
Stock plate lets you slide until the rail grabs. Good for surf and flat. D cut picks the nose up a bit - good for surf or FW freestyle riding.
JD weighs as much as an anchor. Protec is good if cut to stock length. Stock cracks easy. Tom21 is the best - light, cheap, strong.
Shred master is good. Hooks more with less lean, but then gives up all of a sudden and you slide. Overall not a bad plate, but a little less predictable than stock.
IMHO
