Backrolls.. easier than expected. (also what's this called)

[Roflcopter]

Learned w2w about 3 weeks ago and my 180s have been pretty consistent.
so i've been working on my 3's and decided to try a progressive backroll,
my second try i land parallel with the water and a few tries later is was landing but the board was slipping from underneath me. really stoked.
By of the end of the weekend i was riding away just letting go of the rope on my landing. i'll see if i can get some footage up.
what's been your guy's experience with your first inverts and any advice?
also, i landed a back roll with a fs180 completely by accident, what's this called? a hs br 2 revert?
thanks in advance.
