they have both the 421p & 421b. reviews about the 421b seem to be mixed. i've surfed the web, and found one guy on several boards saying it sucked and he had seen some team guys switching back to the p-5. again, one guy's opinion i've found on different forums. while i was @ nitrohouse, i had asked one of the guys, and he said it ripped. same bottom as the p-5 then pulled from mid to top. so there you go - one engine, two opinions. isn't that the way it always works?
