I'm a big fan of the KT range for casual riding for most people - they're just all kinda slow, which may bother some people eventually.
While the KT Atlas and Nomad are admittedly geared more towards the low-mid speed range of the performance side of things, they can both be pushed to much higher speeds. I've used GPS a ton and I'm not far off the speeds on my KT gear compared to the Armie stuff I owned previously. There's just a little more effort required to get them to higher speeds, but I wouldn't call them slow. There is that "raspy" feel coming from the high camber that is interpreted as drag by the brain, but actual speeds are still decent in my experience. Drag racing fast buddies using Armie MAV2s, HAV2s, etc on the wing prove this to me as well. I should mention that the new KT Apex mast notably improves all performance aspects of the KT foils now, as would the PX Army mast for theirs.
