That gearslinger happen to be a Typhoon?
Some of these pics are just great. I cannot get my HDS yet, but I'ma sport the hell out of this light once I get it. I still cannot make up my mind whether I want the High CRI or 170 custom. Great color rendition, or scary blind pocket rocket? I know, I know, I'm supposed to buy them both, but having basement finished and 2 children make this not happening.
Actually, it is the much maligned Monsoon gearslinger (I love it, holds tons of stuff), but I think the straps are pretty similar across the gearslinger line.
I understand your quandary, as I dealt with much the same. If it helps, I bought the 170 first, and if I had to do it all over again, would do the same.
The high CRI is great, but unless you are a photographer or medic, it is a luxury (imo). If I could only have one, it would be the 170. Extremely wide range of possible light output, and when you need it to, it can really pour out the photons.
I carry the high CRI because it makes things beautiful and I rarely need over 70 lumens. The 170 is never far away though, and I consider them a team.
Hope that helps a little.
