Buy an Azure if you're into riding at top speed both up and down the mountains.
The Azure has snappy geometry and perfectly tuned suspension.
This bike rides like it has much more travel than you'd expect. 
4" travel fork and 3.5" travel rear is really all anyone needs for an XC bike.  The Azure is proof!
Lightweight, durable, beautiful and proven.  Purchase of an Azure is a no brainer.
The Comp comes speced with some serious components.
15"size will fit riders 5'-5'6"tall.  Call 914 827 9570 for availability on other sizes.
The major highlight has to be the Rock Shox Recon fork!  This fork is basically a small Pike.  It's my absolute favorite fork for XC ever!
I bombed a Recon fork down the Porcupine Rim Trail in Moab, UT last year.  The Recon never let me down and is still going strong today!
Avid Juicy 3 will slow you down mighty fast!
The Comp has a solid components spec, full of proven winners.
A comfortable seat by WTB, nice rims by DT Swiss, Bad to the bone, Maxxis Cross Mark tires, Shimano Deore and XT shifting duties.  You really can't go wrong with the Azure Comp.
