does anybody know if these are any good?

The blue is the concavity. There are sides that allow tweakage, too.

An excellent beginners plate I must say. It performed for me, and it got me a good start.

MAYBE!

I've got a couple of pairs of shoes with these plates and I've only just started using them. Not much lockon at all to start off with, but once some groove are worn in then they'll be all good

Not entirely sure why Wesker thinks these are incredibly slow; I've found that my Royales are faster on these than on Slo Bros

I would like to describe these grindplates for all of you, as the picture may be decieving. Or maybe my protos are.

The Impact plate is a large grindplate, with a small arch (that can be worn in over time), but from the start it is better than the Slipknot. Also, it is similar to the slipknot in the way that the edges are angled a lot for tweaked grinds like royales to be pulled easily. The picture shows that there are two colors on this grindplate, and this is true, infact they are different materials. The outer part is a rough plastic that feels like soft clay, except it isn't brown and it is plastic. The inner section feels like rubber except it is solid, glossy, and slicker. I haven't tested the plate yet, but from feel I would guess it is slow unless you use wax.

Not really sure what you mean by 'rubber' and 'clay', I've got both prototype and production run Impacts and the plates are identical. The rubbery/glossy thing I can understand a bit since new plates always feel funny, once you've worn them down a bit they should be fine

I, for one, can't stand the way the plate sticks out on the outside edge. It kills me on royales, and it'd be fine for farfs and torqueslides if only there was some decent lock-in :\

Hmm...

I was describing the plate with my Maroon Prabas also, and both of ours came from the same guy. Well at least on my pair the outer section feels rough and has a texture to match that feel.

I have a pair of Prabas, they are excellent even though you can't take off the grind-plate. The plate was designed to be concaved so you could have better balance on rails. Yeh it might kill you on royales, but excellent for anything else.

They are great for royales, exhibit A:

All the plates are plastic. They're quite good but certain plates have major diadvantages to them.

these are good for tweaking tricks but no lock on for frontside/backside....mine are the prototypes so they may be different than the released version i dunno...i love them for royales tho, great tweaking abilities with these plates

No they're fine once used for a while.

What's the difference, do you have pics of each?

......can I see pweez?

By the way, the one shown is the one i call Impact Dual.

Now i know what most experienced Soapers are thinking: "Antho, the dual and the SINGLE are the same plate, its just the dual has two dsnsities and more colors than the Single

My response: True, i should just call it the single, BUT, the two plates are a completely different shape, even the grooves and the oval in the middle dont match up.

.....Whoa.

I'm going 2 sell a pair of white express size 4 shes on ebay

Are these good? Are the Prabas comfy?

These are probably my favorite plates at the moment. They're a lot faster than the bbks/express and pretty good for royales and other tweaked tricks. Shame the shoes they're featured on are pretty hard to find.

They are cool but rare..
