Oh, about Ice over Grass. I've already got an HP Grass one, so I went for Ice this time. Plus, through my experience with using 2 different Heatrans at Nationals and Worlds I found that HP I is better for Heatrans used on Sunny Day Teams (because they can use Solar Beam), while HP G is better for Heatrans used on Goodstuffs teams (because they probably won't have the opportunity to use Solar Beam).
