LOL, you give me way too much credits bro. WAY! You're the wonder doctor here when it comes to springers mate.
But now the $64,000 question... The grease I used is ... [drum rolls] ... None! I cleaned the piston with gun oil, rubbed it off with a dry cloth (leaving just enough to prevent rust, but not enough for dieseling), and then rubbed a little bit of graphite on the piston with a brush. If you see the graphite ball up, you remove the oil a but more, until it doesn't clot anymore. I Did the same with my FWB300S recently, after I used a tad bit too much grease, making it shot below it's potential. No twang, no smelly dieseling, just a smooth cocking stroke and release of the piston, resulting in a nice dry 'TOK'. That's what you wanna hear!
