I have been on HLTA and as such havent had much access to the internet, but my thoughts on the CTS Ruck;
Initially I was very happy with the ruck. In Canada using on PT, both with armour and rigs, and without it performed quite well. Was comfortable, the hip belt/rods transfered weight effectively and as advertised, and the capacity is HUGE! All in all I was impressed, as I posted earlier.
Fast forward to now. We ended up having to ruck into a few locations in our AO, walking around 9km (15 in the case of a few unlucky souls!) or so each time with full battle rattle and rucks. In short, my opinion of the CTS Ruck has done a complete 180. Guys, incl myself, have broken the transfer rods, the stitching at the top of the ruck holding in the aluminum bars has broken, pockets sag and almost fall off when loaded with kit, load lifting straps have broken, and carry handles have ripped off. That is just mentioning the quality issues. The ruck does not fit well at all with full fighting kit and plates over long, hot, stressful distances. Half the guys couldnt even do up their waist belts (the ruck is very unstable IMHO without the waist belt done up), the other half could do up the belts but they wouldnt ride correctly on the hips because of armour and plates, resulting in the belt sitting on the hip "pocket/flexor region". This caused bruising, blistering, and general discomfort. I have ditched mine and gone back to my 64 as has almost all of the guys in my pl.
