I don't have a problem w/the weight limits. I do have one w/the high performance landing requirement. Why should a Noob be forced to do a double front riser approach? He or she may have no desire to ever do such landings.
Because at some point he's going to land at faster than trim speed.
Maybe he gets back low from a long spot, needs to avoid an obstacle, or is just chasing the wind sock. He doesn't make a flat enough turn and picks up speed. Or perhaps he'll be holding brakes so he doesn't over-shoot the landing area (it works with modern canopies when there's a head wind) or to let some one else land first and he gets a surge close to the ground. In all cases he needs to flare from faster than trim speed.
Double front risers are the safest way to get that speed in a controlled setting because getting out of the resulting attitude only requires a pitch axis correction, the canopy will respond relatively quickly to control input because of where the jumper ends up relative to the canopy, and the jumper is traveling in the direction of landing during the entire maneuver so he doesn't conflict with the pattern or hurt himself trying to finish a speed inducing turn.
