Arione is a cracking saddle.... aside from miles and miles in training rode the full distance Paris-Roubaix sportive (250km with 50km of pave) and not a hint of soreness. That said, everyone's undercarriage is very different
It's worth splashing out on some really good shorts. You can't beat Assos in my book and don't forget to slather on the chamois cream Udderly Smooth is great.
