Glad you made it back Scoot
That's a loaded question as it's hard to choose between the two. They are very different kites. Consensus though seems to be that the 1.5 is a better all rounder and if you're forcing me to choose my desert island rev then it would have to be the 1.5. But before you head for the lifeboat try and sneek in three 1.5 EXP rods (or Skyshark P300) as well. Using these in the leading edge instead of the heavier and more rigid SLE spars will let you fly in lower winds.
Have you flown Revs before?
