Hi Help!! ...I am about to upgrade from a Hardtail to a new full susp. bike. I have narrowed it down to a choice between the Scott Spark 50 (R14600) or Silverback Mercury 2 (R15990). The Mercury has better spec's: (Rockshox Reba, and combination of XT/SLX with SLX shifters) but only has 100mm travel and is 1kg heavier. The Scott has Rockshox Recon, XT /SLX and Deore shifters, but 120mm travel and lighter frame. Have heard the Scott is also a particularly responsive ride and good on the tight switchbacks, and climbs like a hardtail when locked out. Can't find any reviews on the Silverback....Any advice?
