Hey guys,
A while back, I converted my Silent Killer to a Slide Swimmer. It wasn't easy, and i'd say that it is far from perfect, but she swims now. After removing the skin, I added a pounded out weight to the front weight slot (Just enough to get a nose down sink). After that, I added about a half of an egg sinker (haha so scientific) to the slot that housed the bill. It is slightly heavier than your regular Slide Swimmer and swim is not "as" fluid, but it works.
Here is my first outings with her.
