Ver 1: I’m not all that proud of this one... it was difficult... sometimes the pants end up down around the knees. I’m already working on version 2, which I hope will be more accurate. It seems to answer if you push the weight. I've been up for about 2.0. Feel free to give it a try and get back to me if you find the ultimate setting :)

Ver 2: Alot easier to get that whale tail than version 1 i think. be my guest and try it out
