wanted to get new blades but unsure wether to get the coronation ace lites whcih are prettier but parallel or the coro ace parabolics as from my research parabolic blades help with edgework and staying centred.. same price for both just unsure what to go for and would appreciate any advice 
I'd recommend the traditional Coronation Ace rather than either Parabolic or Lite.
Skaters at the CA level rarely have good enough edges to make the parabolic feature worthwhile, as it really doesn't kick in until you have steep edges, so is a total waste of money.
I haven't found many skaters who actually like the Lites, plus they are harder for learning catch-hold spins and spirals. Lighter weight equipment is a handicap in the long run when learning jumps, too. Save the lightness for when you need an extra boost to get triples - or doubles if you're an adult skater.
Of course, if the traditional Coronation Aces are out of stock everywhere...
