Niodes. It has a Trample shield of 11%, Shield of (20) with the vulnerability of Speed -3. Pretty affordable really and an anti Trample shield comes in handy no matter the percentage, the additional shielding at 20 isn't too shabby and the price of a movement/speed vulnerability really isn't that bad.
As large mechs are slow to begin with it isn't like these are going to totally drag your mech down unless you stack them. But given some of the newer dino based mecha have trample shielding this could be a fun little add on to them to see how much you can deflect at one time. Not much more really to say here, it's a shield it does its job and only slows you down a bit. There are worse pieces of equipment out there with worse vulnerabilities attached to them.
