ULA ohm vs. cdt load transfer

I think if your carry weight is going to be +25lbs I would go with the Ohm. Not a huge price difference and the extra volume is a plus. Is it going to carry significantly better than the CDT? I think yes, but not drastically. Hopefully someone will chime in that owns both. I have the Ohm and have owned packs similar to the CDT, but never had the pleasure of carrying the CDT.

"With a load of 25+lbs, will the ohms's suspension have significantly better load transfer than the cdt? or at least enough to justify the extra 5.6 ounces?"

Absolutely. Although comparatively equipped, the difference is actually just a couple of oz.

The ohm was my original choice, and it looks like I will be sticking with it. The main reason I was considering the CDT, was because the pack will likely see weekend loads more commonly than the 25+ lb loads where I expected the ohm would prevail…

However, the compression system on the ohm should handle small loads nicely, and with plenty of room for fishing gear or alcohol.

Scott – the compression system on the OHM is really good. Probably the best I have seen as the side cordage will tighten and compress at several points on the pack, rather than just one with the CDT. Maybe buy both and return the one that does not meet your immediate needs?

I agree, the few oz. gained in the Ohm over the CDT is meager considering you open yourself up to a few pounds more load capacity and comfortable load transfer for heavier trips with the Ohm. The 1.6 oz. carbon/delrin hoop functions extremely well and the assistance doesn't go unnoticed. I've only used the Ohm with full loads all under 15lbs. for 3 and 4 day trips and I've found the Ohm to be the ideal pack (for ME) even toting low weights. ULA recommends a base weight of 12lbs or less for the Ohm so I think the Ohm will suit your 10-11 lb. mentioned base weight plus leave some wiggle room for rod and booze.

By chance, I weighed my Ohm piece by piece this morning. Medium Torso and Large waistbelt.

Ohm with no backpad, cf hoop, or hip pockets is 536g (18.9oz).
Backpad is 32g (1.1oz)
CF Hoop is 47g (1.65oz)
Hip Pockets are 31g each (1.1oz)

This is compared to the 17 oz for the CDT. 2 oz difference for the extra capacity. The Ohm definitely has better compression ability with the weave pattern of the string. I think you will be very happy with the Ohm.

The one downside is once you get up around 25+ lbs, the hip belt doesn't provide much padding. IMO, the hip belt is more designed for stabilization and nut as much carrying weight. My Golite Pinnacle does a much better job at the larger volume, heavier weights than my Ohm does. However it doesn't compress down as beautifully as the Ohm.
