Though it can be argued that those who use their own controller will know the timing and whatnot, the fact is the person without the spring has the "better controller" for the game. If you like it that much, then you should either switch over to one of the THREE OTHER SET-UPS or reroute your controller to something to the effects of what Eten has.
Example: Someone not willing to learn wavedashing in Melee compared to those that took the time. You can learn the **** timing with the spring as well. It's not that hard. Hell, if you've played Wifi matches you know you have to adjust your timing to be earlier to do well. It's a mere adjustment, and doing a non-aesthetic mod like that is just an example of someone who for whatever reason has no heart in learning the timing, yet they can wavedash, powershield, l-cancel, etc, on the dime in Melee.
Seriously, I don't even know WHY this would need discussion. It's simple little facts.
