well they do have a bit more mass, so I'll admit they cant be shaped AS easily, but they can still be shaped without a problem. Regular steel cant be shaped as easily as aluminum but you can still do it, so the "cant shape it as easy is a non issue, Its still easy.
I tend to travel in long straight lines, ride a Walker on alot of gravel. My horse used to forge and pull her shoes off the front. He drew some lines talked it over with another farrier, went with NB's in the front now I get 100 miles on a set. The same farrier puts normal shoes on my GF TB X who rides similar terrain, tells us to leave the little arab barefoot, and says to use renegade's on the front of my other Walker. I'm not a farrier, or a pro, just a rider. Thats why I pay him, to figure those things out for me.
