I've only flown a Warrior once, I normally fly an Archer, but I found there were quite a few differences.
For climb-out on the Archer I was taught to fix 80 kts, but the Warrior wouldn't keep that speed unless the nose was very low and it had nil rate of climb, so I had to use approach speed - 70 kts.
Also when slowing down on base I found the speed bled off really quickly compared to the Archer - I had to keep a very close watch to make sure it didn't get close to the stall
But on the whole they are similar - take it easy and you won't have a problem.
