The straight out hang is what the skids are for. I always hung in an executive type chair. It has a long seat that supports the legs (thighs) all the way to the knee. I put the 4 inch pvc pipe extension on the edge of the chair and hung over that with the skids resting on the pvc pipe. You will lose a little weight to friction, but if needed, just go up in weight.
If your chair is not that long in the seat, get another chair to put in front of you, and a rope extension. Then, put the rope extension with the weight attached over the back of the other chair. You will have to put your feet up on the other chair to hold it.
As relates to soreness, have you arrived at the point where you can hang BTC? It may take a while gradually sliding your butt down in the chair before you can do this. But it is a great hang for the ligs. Usually, you have to go down in weight to do this.
