My wife's out of town, and we had both the Stucchi and Mistral crossovers in stock, so I took the set home to try for the weekend and gather some impressions. Previously, I had had an FBF crossover on my bike and had liked the top-end rush it facitlitated. Then, because the FBF crackes, I switched back to the stock crossover for 6 monthes.   First, I tried the Stucchi. It's a really nice piece. Heavy construction, much of it double-wall. The design is the same as that of the FBF I had mounted
