TWM, Moddiction, BLOX, they all make heavy knobs. I recently got the blox one at 495g, and I love it.

 

Thanks for all the input. I think, I'm gonna go with the skunk2 knob, and if I like the increased weight, I'll work my way to moddiction.

 

I have a Voodoo (countersunk but near equal or lighter than stock) and I like how it has changed things. Shifts are a little more notchy and direct. I don't think either would cause or prevent missed shifts.

 

I personally use a lightweight knob. Compared to the stock knob, shifts are much more direct, shifter doesn't slop around, and it's countersunk. i've never had any experience with a heavy countersunk knob.
I shift a bit like the OP. going from 2nd to 3rd, i push it up and out of 2nd gear, let the spring move it to the middle, then just push it up into 3rd gear. i barely ever grip my shift knob using my whole hand.

 

mis shifts might be more due to technique.

 

With your style of shifting ... it wouldnt make it harder but buy one thats not round. im used to palming it up(1st,3rd,5th) and using finger tips to go down (2nd,4th,6th) heavy= easy

 

I was going to ask.. how does the shape affect the shifting?

Is the round better than the oem style/shape or just different? I'm debating picking up a moddiction one, but am now debating whether an oem shape one would be better vs. round..

 

I have the moddiction countersunk knob.

It reduces notchiness but remember not to get lazy with the shifts. You still need to follow through with your throw. It's easy to miss gears due to laziness with a heavier knob because it feels like it's going to "fall into gear".

With the lighter stock one It was easy to tell if I wasn't all the way in gear.

Just takes getting used to it. I personally love the heavy shift knob.

 

The heavier knob becomes easier and 'smoother' to operate in day-to-day activities. While in track environments, the 'smoother' operation tends to make the individual gears a tad harder to find when quick shifting. They become vague. That notchiness of the light knobs tends to help feel for the correct gear in high-speed environments.

 

Look into the ScienceOfSpeed Zanardi replica knob. It's nice and heavy, but sits a little taller than stock. I haven't had any issues with misshifts, and the shift action is extremely smooth.
