It depends on what you are looking for in a touring boot really.I have the Scarpa Spirit 4s and the Scarpa Tornado Pros. The Spirit 4 is now my touring boot though I had used it up till today for everything including the resort. They are a little flexy for my liking, but, they are a touring boot, what do you expect? :-)The Scarpa Tornado Pro is a straight alpine sole (as opposed to the rockered sole of the Spirit 4) and is more "geared" towards resorts where you will be hiking and slack and side country. Not to say you could not use them as a straight touring boot, but, there are better options if that is what you are soley looking for.The Black Diamond boots...meh. :-/ I tried them on...wasn't that impressed with them. Then again, I NEVER skied them, so that doesn't mean much if anything at all. I tried the Factors on as well and for my foot both left a lot to be desired. I have heard RUMORS (stressing rumors here...no first hand knowledge) that thy walk/ski mode pin has been breaking in a few of the Black Diamond boots. I would be surprised if it was true, as BD normally has awesome quality in their products. But....Also, it depends on your foot. The Spirit 4/Tornado Pro is geared more towards wider feet and collapsed arches. The Black Diamond line is a little narrower but still should heat mold out if you need them to. Also, the Scarpas come with Intuition liners (not sure about the BDs) and I feel this liner is flat out the best on the market right now! Get them heat molded at a boot fitting professional and you will have the most comfy boots you ever have had.Let me know if you have anymore questions. :-)
