Was definitely thinking about the T3. Had one for my old Model IV, but was not able to put it on before the plane was sold. Would you say it’s worth the price increase over the other options offered from the factory?

@CTFox,
I run one on mine as do a few of my Fox buds. I'm a huge believer in "cry once, buy once". Will the others springs do the job? Sure! As for is it worth it? I say yes but ultimately, that is your call.
