I've held back on buying the TTi because I'm afraid that the cap crimper will have an impact on the utility of the pliers. Since you EDC it, I'd be very interested in your opinion on that.
I wouldn't say I stress my pliers, but I don't hold back on them; so strength has not been a problem. I do a fair amount of work with the needlenose; there is enough surface to use. While I'm not crimping any caps, I have occasionally found them semi-useful and not a hindrance. That portion of the plier jaws is good for holding a nail in place for hammering or holding the bail on a pot handle when camp cooking.
I also have a Charge Ti that does not have this feature, thinking maybe I'd like it better. I have found that the cap crimper doesn't bug me much, and the S30V holds an edge a bit longer than the 154CM steel on the Ti, so I've stuck with the TTi.
