Modified 5th link/torque arm

Was wondering what everybody was using for 5th coil/link arm....
I was looking at a guys modified (Keith White imca #3 modifed #1 southern sport mod this year) and he doesn't use the 90/10 torque arm shock just the biscuit bar on his Hughs car. Any thoughts/ I though this might be a little viscious on and off the gas but he looks really smooth and said he thinks the shock hurts more in the corners than helps as in effecting roll much like moving the pull bar to gain tracksion on either left or right side tires
