Very important point number 1: Wreckers' Slab (VS 4b) is in Cornwall, not Devon. Round here you could get into serious trouble for that mistake, almost as bad as putting the cream on before the jam.
More importantly, it’s not really a suitable objective for an inexperienced climber unless you can find an experienced leader to take you up it. To lead this, you need to be happy on a multipitch route with loose rock and limited protection. That said, it’s technically very easy for VS, and a great adventure.
If you’re looking to get into multipitch trad, the East Face of Tryfan would be great.
