Interesting perspective!
I currently wear the coronation ace lites and my coach would like me to upgrade on my next blade purchase. Options are either the Pattern 99 (which is what she wears herself) or the Matrix Supremes.
By your perspective above, the Pattern 99 then would be the most obvious choice even though she says I'm so used to jumping on cross cut picks, I'd have an easier time pick wise with the Matrix Supremes.
Something to further discuss with my coach when the time to upgrade comes (my Coronation Ace lites still have several sharpenings left).
I would be cautious of taking advice based so heavily on the differences in just the pick design. The purpose of the pick is pretty simple: To dig in the ice. All designs work pretty much the same. Even if people have their preferences, all have been used in high level skating. A straight cut will dig slightly deeper to the ice than a cross cut. But the the actual blade profile plays a much bigger role in how a blade actually works for you (or doesn't).
In the Matrix, you're looking at an even flatter secondary rocker to that of Ace or P99. That might work for you, or it might not. But it is a bigger difference than just the toe pick, in my opinion.
If you really wanted a P99 profile with cross cut picks, you could also contact Paramount and ask them to make you their 27'' ("P99") blade with cross cut picks. That would be pretty cool, I guess.
And, if the cross cut pick design really is your main criteria, then a Gold Seal or Phantom are also possible options for upgrade. Or, their parallel edge (like Ace or P99) "equivalents" from Paramount (12'' for GS, 17'' for Phantom).
Personally, I don't think you can compare the P99 or Gold Seal to either the MK Pro or Coro Ace.
They're both pretty unique as are most other blades.
While I agree with the sentiment to a degree, it's not like we are comparing rocks to oranges here. We're talking about figure skating blades that should conform to some pretty well defined manufacturing specifications. It's not particularly useful or helpful to anybody to just simply state "all blades are totally different".
And, we can take this to the other extreme: All blades are
unique, including any two individual blades carrying the same name and coming from the same manufacturer. After all, techs are routinely returning blades with too high tolerances that don't conform to their idea of what the actual blade profile should be. And, a single botched sharpening can turn a Gold Seal to effectively a P99 with tapered, slightly longer blade, cross cut picks, and higher stanchion.
