2 cLPLas (torsos) + 4 cERSLas (arms) with a TC1 and lots of DHS is one of my favorite builds on the SCRs, especially for CW. This one looks a bit hot for me, but if it works for you - all the power to you.
It is hot. Two alphas take you to about 83%. I have groups for the left and right arm. Once you get high on heat, I try to just use the 4x cERSL.
