Lower CG is better for handling. If you went HD 1" lower dprings in back you can crank the t-bars down to match. Your heavier bars will help keep the front off the bump stops with the lower height. I have .92 bars on my 68 and cut 1/2" off the front rectangular bump stops on my bandsaw. I can put my finger through the gap. You'll probably get a LOT of opinions so be prepared.
