Really good points K. I try to fish a tight, controlled line with no slack while lake T fishing from a tube. Primarily casting to bulging fish or structure and not so much mooching or trolling. I practiced the same approach "western" fly fishing for 30 years including the use of muted DT/WF line colors notwithstanding a longer leader. Conservative cast not a blast, let sink a bit, then slowly raise the rod tip rather than strip - sort of a Leisenring lift. In 4 years of T fishing, I have come to the same conclusion about stillwater presentation and stealth. So I will stick to the 3 ft. 6X tippet with direct connection to the low -vis level line, for now anyway. I like the control, ease of casting and simplicity above all else.
