I’m 5’11 and 3/4 and ride a large – from what I know a medium would be too small for you. Compare the size with your Orange – the Large Tracer is 18.5 seat tube and 24 Top tube, but rides low at the front.
Tracer 2 or Tracer VP btw?
I have a mate with an ASR 5 so here’s my opinion.
The ASR is a great all round bike, a standard build 3-5lbs lighter than the Tracer, and will blast most trail centres and singletrack. For big jumps and abuse though, the Carbon swingarm would make me nervous.
The Tracer (both) is stronger at the rear end. The VP can be built up as “Long Travel Trail” (As is mine at 30lb, ridden in 5.5″ mode, Revelation 150 dual air, Mavics Thompson hope etc) or stronger All Mountain (160 Fox 36, stronger wheels, kit and so on).
IMO, the Tracer is the bigger burlier bike with the ability to be really good on the climbs due to the second gen VPP. Having said that, my friend on the ASR has ridden everything I have.
I have a feeling from your description you’d be doing bigger drops (big days?) and in which case I recommend the Tracer.
The Tracer can be a bit like owning a TVR – they work or don’t and can be a bit hit and miss (loosening pivot bolts, trick shock setup, the VP really isnt good with the Fox RP23 BV in some people opinion) but great when it works (which for me is 99% of the time). The ASR (and Yeti’s generally) have issues with those carbon swingarms……
Finally, the difference between the suspension action (single pivot swing link on the Yeti, VPP on the Tracer) is quite marked – the feel of this alone may force you one way or another – so try to get a proper, lengthy test ride if you can, with the shock pressures set up for your weight.
A tough choice IMO, both are lovely bikes.
