Heavy or lightweight flywheel?

Very interesting info I did not realize. I imagine it’s healthy torque wise. Trans is a ViperT56 with 2.97 1st, 4.10’s out back and I can cruise along shifting at 1300 rpm and cruise in 6th gear just above idle with no jerking. I can take off on a slight grade from a dead stop in 4th. What you mentioned about it settling down a rough idle definitely has my attention. My engine has a fairly radical idle and I have to keep the idle at 1k to avoid my headers banging the steering arms and or torsion bars. Even with the TTI headers you guys it’s a tight fit. If I go lighter I’m concerned it’ll become even rougher. Now I’m really puzzled on which to get. Very disappointed with my Ram flywheel just letting the rings gear loose like that so quickly. I don’t feel good with the welds on it I’ve been told it isn’t a good idea especially on a motor that likes to wind up. What’s you all opinion on that? We put 6 good tig welds on it but not comfortable
