I can officially say that I am impressed so far. I bought two sparks Friday, a base model 2up and a 2up HO with IBR. My son and I put them in the water Saturday and I am impressed. The Sparks handle great and I can not wait until we get them completely broke in so we can really cut loose. What is the recommended break in period? The dealer told me 20 hours and that does not sound right. Any info would be greatly appreciated.
