Raking vs spp is the wrong paradigm, there is no idological dispute between the two. Both are picking.
Raking and spp or Spp and raking are the way it is, if your good, thats where you'll be.
The reason raking is disputed at all is because some consider it "too easy" and new comers are discouraged from even going there because you'll never come back to SPP.
Yes, you can rake open locks with multiple spools and serrated pins. Use a well sanded bogota rake and light pulsed, tension.
So if you go raking and never come back to Spp, no big deal, but all the good ones are good at both.
Just my opinion
