I flew through the new airspace on Thursday 28th,the day it was implemented.Absolutely no problem whatsoever,an early call at Ferrybridge
requesting direct to Gamston was approved immediately not above 2500 feet.This track took me almost overhead DSA.The new airspace looks complicated on the map,and will catch people out for a while,but as far as transiting the zone,commercial traffic permitting,the controllers are more than helpful.Also no problem on the return trip!
