I like the verb in my Blues Junior BETTER than in my Supersonic. The SS has too long a decay for me, too splashy. (I don't do surf). Since they're both Accutronics tanks, what's the difference? Spring length/# of springs? Would it be as simple as buying a Blues Junior replacement tank and putting it in SS? Also, difference between Accutronics & Ruby (for same length/same #springs)?
