What limit's are you playing? I assume they're pretty low. IMHO your stats of 6 of 7 won at showdown is too close to the 9 won without showdown. If your stats of pots won without showdown are 2 to 3 times higher than those won at showdown THEN they are truely scared of your play and it may be time to loosen up.
Also what's the max buy-in? What's the tallest stack in comparison to yours? If your way ahead and getting to much respect THEN it's time to mix it up and lose a few, donk a few hands and tighten back up.
I don't like showing and only show once in a while which is rare to friends or opponents who I have respect for and from who I know I have respect.
To spur my opponents I'd rather get caught bluffing
or making a donk play chasing an inside straight or backdoor flush.
