I haven't ridden the Nickel but I've built up a couple and ridden them around the parking lot. I think the Nickel is quite a bit heavier, and has as much in common (in terms of design) with the Super Light as it does a Blur. The SL and the Blur are very different beasts. I would imagine the Nickel would have ride characteristics of both.
The Nickel is as much a single pivot frame as anything, and would probably produce a little brake jack. The feel of the travel through out the stroke is supposedly very similar to the blur, but the ride as a whole should be quite different.
If you don't have the money to get VPP then consider APP. There is a reason the APP bikes cost less.
