I've been watching a bunch of fights from these two recently, and I'm quite happy picking Arce. At 108, both were a little bit unheralded, and great fun to watch. Arce had better skills than Yaegashi IMO, with more polished feet and a much shaper offense. I feel like Arce would fight in a manner more like he did vs Carbajal, using height and reach to let Yaegashi come to him and trade. Which I think is when Arce paints him on the way in, and then gives us a great, great fight on the inside. It'd be a bloodbath, but I think El Travieso was a better fighter.
