3 hole, always. Never yet felt comfortable with the car using 2 holes. Maybe different if I were to try drilling out the pistons, but I'm lazy, and the 3 holes work fine

HiH

What feel of the car does the 3 hole piston give you that is better for you than the two? Also, would that be with a kit/similar oil?

I just got my WE up from my 416 and the setup is a bit different than what I had been running. A good day of testing will help me figure some things out though!

Usual ranges of oil, from 30wt to 50wt. Generally I found a 40-50 good on the front, with 35-45 on the rear. I'm currently running 450wt all round indoors, and probably wouldn't change it too much for outside.

As for the feel, the 3 holes felt smoother and more consistent to drive, and coped much better with bumps. That's probably due to the reduced pack in the shock.

A good little guide on setting up the shocks is as follows (this is taken from Richard Taylors tuning tips for Losi off-roaders, but the same applies on-road)

To increase pack, go from an orange piston to a red piston (smaller piston holes = more pack). If this makes the car feel too stiff in roll, you can at the same time lower the weight of the oil, by 5 to 10 weight, this will still make the car stiffer initially but still have a soft feel once moving.

To decrease pack - go from an orange piston to a blue piston (bigger piston holes = less pack). If this makes the car feel too soft in roll, you can at the same time increase the weight of the oil, by 5 to 10 weight, this will still make the car feel softer initially but will still have a stiffer feel once moving.
A car with less pack will cope with bumps better, but may roll more, so go to slightly heavier oils too counteract that.

Thanks for the help Ed!

I am going out to the old AV Tamiya track (well...I can dream since waking up is hard) and do a little testing so we'll see how it goes. from what I gather though, the changes in setup from my 416 to 416WE will be minor. I don't like the 3.5 rear toe angle, and running 13.5, it's way too extreme for me.

just tested my WE and honestly i dont feel the difference from my 416 with the Jilles set up.
Do you have the 416 with the short arms, just upgrade the topplate , dampers and the motor mount and save your buck

The top deck isn't even really an upgrade, but a tuning option, right? All I really want is that and the new belts. The motor mount doesn't really seem like a big deal unless it's a lot lighter, since I'm not racing mod.

What's the story, exactly, on the new dampers? Do they hold more oil, or just smoother?

Tamiya dampers havent changed since the 90s. Just different coatings, colors and different o rings.
