My experience,
1 hour C150 to Cherokee (at 25 hours TT, during PPL training.)
1 hour Cherokee to Warrior, made up mainly of circuit work nailing the approach speed to avoid float. (at 60 hours TT, after PPL training.)
The Cherokee (slab wing) and Warrior/Archer (semi tapered wing) are very similar in most respects, but the landing behaviours are different enough to warrant familiarisation..
