Given that they appear to have only been on sale this winter they may not have much of a reputation. Over the years on VFTT its usually takes one or two full seasons for durability issues to surface unless there are real obvious issues out of the box. We have had a "normal" snowfall winter in the whites (please note we had a couple of abnormally low snow winters in prior years that spoiled the winter hiking community) and its the low snow years that seem to really pound on snowshoes. Therefore this winter may not be a hard year on snowshoes and thus the reviews may be great . As an example , it took about two low snow winters for MSR Lightning Ascents to go from the "best snow shoe by far" acclaim to "somewhat fragile for the whites" on VFTT. Several members had their broken lightnings replaced with the prior Denali Pro which have a more bombproof but not completely bombproof reputation. Thus in buying TSLs you may become an involuntary product tester in the whites where good shoeshoes on occasion go to die. The TSLs claim to be made in VT which is plus but their website history section states "All TSL Snowhoes are produced and designed in France" so I am curious on the extent of the local production and how long they will be here to answer the phone.
I personally like a rigid snow shoe that can be kicked into a crusty slope to climb up it, the TSLs design appears to be great for walking but the flexibility would appear to be less good for kicking in steps.
MSR is reportedly considering bringing back the Denali Pro next year and Mountaineer in the ADKs still had some stock so they may be an alternative. Considering they are just about the standard in the whites its hard to justify going with a unknown.
There are some diehard fans of 'boutique' shoes as well. The major take away in any discussion is to keep to the same width shoe as everyone else (8-8.5 x 22-30) or else you won't readily fit in the track.
