...but really believe that that the incans are much better performers in the outdoors...
Very true. While I love the latest LED lights as much as anyone, currently there simply is no LED on the market that can provide the throw and color rendition of an incan for the same weight/bulk. The A2's incan beam is whiter and has much more throw than any LED of the same package size. I feel this "punching power" is worth having over the LED designs.
Have a look at these beam shots. I think they really tell the tale:

I was confused by the statement above that the A2 has
...not very good runtime on primary level...
compared to the HDS U60. The A2 is conservatively rated for what has been measured at 75-80 lumens for 50 to 60 minutes, while the HDS website says that the HDS U60 puts out 60 lumens for 20 minutes. However I am impressed at how you can program the HDS in so many ways. That would be very useful.
