For anyone reading this in the future, as there seems to be very little information out there on the Peakspeed lineup:
I went with the 7700s, and after a couple of small, resolved issues, am quite happy with them. The fit, to me, is extremely similar to the G75 XI (blue piping, not green). Coming out of Jetspeeds that I was in last season, they feel quite similar, but with more forward flex and a slightly lower ankle (I drop an eyelet in the Jetspeed, not in the Peakspeed), and are roomier in the forefoot - slightly wider, slightly more volume from bottom to top. Now, something that should be said - I referee. I am often in my skates for long periods of time. Using this week as an example: On Monday I was in them for 3 hours; all but 15 minutes of that was skating/standing on ice, I'll be in them 5 hours on Saturday and 3 hours on Sunday as well as 90 minutes each Tuesday through Friday. The perfect fit for me reffing is different than the perfect fit for me playing. If I was only playing, I'd definitely still be in the jetspeeds. But they weren't going to cut it long term reffing, they just pinched my feet too much after the first game. So I like the slighty roomier feel. Somewhat similar to the Tacks I tried on in the store, but the tacks felt like being in cement; wayyyyy too stiff with no flex available. The Peakspeeds are definitely stiff, but I'm still able to roll my ankle all around. I did have the Peakspeeds profiled to 11', like the old Grafs have always been.
I had two issues with the skates, both have been resolved.
Footbed and Heel lock. The stock, foam footbed in my previous Graf Skates - going back to those made in Switzerland - was phenomenal. Really, I loved them. I even used them in my CCM skates. The ones that came with the Peakspeeds, and this may have been a mistake as it was prior to Vaughn buying them and QC wasn't all that great from what I understand, looked the same but were nothing but rivet covers. The foam was not rigid whatsoever; I may as well have used a cotton rag instead of them. I reached out to Graf (Vaughn), asking about it. They sent me this footbed. This solved the Heel Lock problem that I had. This footbed was much more substantial than even my old footbeds, I'm thrilled with it.
There was a small piece of molded plastic/fake leather that was sticking up above the ankle pad on the top of the boot. It was rubbing a very small part of my ankle raw; you could tell it was from a mold and just went a little bit too far. I just cut it with a scissors - we're talking about 1/2 mm here - and the problem was solved
My only complaint left about them is that they weren't using the green logo at this time. That has been resolved.
One other thing: I had an issue. I emailed Graf (Vaughn). Their reply was so over-the-top, out of their way to make me happy. If I ever win the lottery, I'm heading to their HQ and dropping a boatload of money on a custom skate and custom Eagles, based on this experience alone. Definitely happy to support a small business here.
