I need a new pair of spikes, and I was looking at the Saucony Ballistas. Has anyone had or have them, and how do you like them? Are they enough of a shoe for a 3200? Also, are they durable enough to get through at least one full season? I have the carerrra xc 2s now which have ripped after only a couple XC races and most of track under both my arches. From the pictures online it appears that they have a thicker mesh than the Carreras, and since they are a mid d spike I would assume they have a sturdier upper, but I have no clue. Thanks
