I'll consider myself called out.
First, the disclaimers: I've been riding hardtails and softtails, 26" and 29", for over a decade. I test-rode two dual-suspension bikes in the last year: dirtydoug's DW Sultan and ignazjr's (Dave's) Tomac Snyper. Thus, I don't have a lot of basis for comparison. I come from an XC/single-speed racing background, and with the decision to go for longer rides on more difficult trails, I was getting frustrated with the lack of versatility and fatigue I was experiencing with very long or difficult rides.
That said, I've been very pleased with the way the Tracer rides. I had some initial concerns getting the suspension set up, but after two or three rides and some input from Dave, I was able to sort the suspension out to where I'm very happy with the bike. Now that the bike is working well, I am able to go for long, difficult rides that used to leave me frustrated and uncomfortable. Now, I'm disappointed when I reach the end of rides, particularly stuff like Little Raven/SSV near Boulder, where I feel confident cleaning the whole descent (except for those two spots where trees are on the trail right now).
Dave and I built the Large T29 with a TALAS 120 with a tapered headset. I run the rear in the 5" setting, and I tend to use the front lockout and rear pro-pedal, and drop the front for longer climbs. Dropping the front end makes enough difference in the steep-climb handling for it to be worthwhile to reach for the switch. Front and rear lockout/pro-pedal leave enough compliance to get the bike through all but the chunkiest climbs. Climbing without the lockouts dramatically increases the feeling of the weight of the bike (just over 34 pounds).
With descending, as I mentioned above, I feel very confident that the bike will go where I want it to. The big wheels and suspension devour almost anything I encounter. I haven't been off of any giant hucks (more than a couple feet, although I like to get some air under the wheels off of rollers when I get a chance), but the tail seems really plush, and the 120 in the front seems plenty adequate for local uber-chunky descents.
The bike is set up with wide bars and 90 mm stem, to go with the tapered headset and 15QR in the fork. The front end feels very stable. I don't notice any flex from the fork, and I haven't run into circumstances where I felt the head angle was too steep (i.e, no sense of pushing/washing out the front end).
As I mentioned in another thread regarding the VPP, there is absolutely
no pedal feedback from rear-suspension activity in climbing, as compared to a very definite sensation of the tail's activity on a DW Sultan. The Sultan really felt like it was "digging in" on bumps, but the Tracer just motors along. Climbing is very comfortable.
The only complaints that I have with the bike are similar to those of other 29ers (On-One Inbred 29, Voodoo Dambala, some James hardtail, and a Salsa Dos Niner). I've always felt like the bottom bracket seemed low, compared to the sensation of the bike riding a little further away from the ground. Also, like other 29ers, the bike feels a little long on very tight, steep switchbacks. However, I think these complaints are endemic to 29ers, and would only be a surprise to someone who has never ridden a big-wheel bike before.
As a side note, I built the bike with a Rohloff gearhub in the back end. I was worried that the weight of the rear wheel (~8.5 lbs!!!) would tend to adversely affect the rear end's compliance. I haven't noticed this to be the case.
To finish the disclosure, I haven't ridden other dual-suspension 29ers (desides the DW Sultan). I can't offer a subjective comparison with, say, the Tallboy, or that Specialized thing, or a Pivot or Niner or whatever.
To be honest, I feel like the T29 works very well for me. The bike seems to work very well for the way I ride, and what I like riding it on.
