Impacts have no lock-in whatsoever, the plates are basically flat and I hate them. They're useless for rails until you wear a groove into them, and since I never grind ledges my Impacts are nothing more than a health hazard

The one good thing about them, though, is that the outside edges are concaved (see the picture of the plate http://www.solidgrind.com/grindplates/soap-shoes/impact/">here, the concave is the bit between the left edge of the plate and the edge of the blue section, you can kinda see it better in three dimensions on the http://www.solidgrind.com/shoes/soap-shoes/dash/">Soap Dash). This is handy when busting torqued grinds such as royales and farfs; the two edges formed by the concave help lock the torque in (unlike BBKs where, as the edges of the plate are rounded, the plate can slide forwards or backwards and you can lose the torque). However, this again is useless you've worn a decent groove in your plates

Also, bear in mind that Impacts aren't replacable, whereas BBKs can be replaced when worn down, or simply swapped out for one of the other types of removable plate. Generally, the shoes with Impact grindplates are a bit lighter than the ones with replaceable hardware but, as I've said, the plates are a bit gash unless you're going to be making love to curbs all day long

They've still got the arch, and the two bar-type deals give more lock in than the impact ever would out of the box.

...what

i'm so confused at what XSIVE7 said too, but i'm getting some shoes and i'll throw on BBK and see hwich is better, express or BBK. I'm thinking express = easier lockon, but BBK = more tweak and can handle wider rails (like square rails. Becuase of hte raised non slippery sides to express, you can't really do much other than circle rails.

WHOOO! good for you dude! I bet ur gonna LOVE the slo-bros......If you never had them, prepare to feel intense and VERY secure lock-in and control

I've got some Scabs on their way with the Slo Bros as well, really looking forward to it. I have one SloBro that I got from Steve a while ago and I love it.

*raises hand from corner* And the Express too.....Every bit of surface on the Express are grindable as well.

I apologize if my last comment was very long

I got my SOAPs today!

Lock-in on these Slo Bros are absolutely AMAZING.

Only thing I have problems with is the fact that I should get my footing right, because of the lock-in-ness, it doesn't feel as secure as it should if not in that "rib".

It's really slippery. xD
