Strengths: Light, fast feel, excellent fit and well cushioned. Good amount of support for such a light shoe.
Weaknesses: Not sure how long they'll last, and haven't yet tried them over longer distances
Overall: I'm reasonably light and quick (8 1/2 stone, aiming for 3hr marathon) but overpronate quite a bit. As a first venture into lightweight shoes these were made for me. Felt great from the start and had my gait checked after 150 miles and they're still doing the job. Have mostly used them for 5/10k, shorter training runs and speed work. I've been told I could get away with them for the marathon, although I'm tempted to try the updated version for the extra cusioning. However at £30 a go in TKMaxx I'll be stocking up on these! Don't have anything to compare them wtih as Asics DSs just didn't fit!
