I too had trouble switching, though I did (from MK Dance to an older generation Matrix Dance, Supreme and Synchro) - but have never really been happy with them. I did it for economic reasons, with an earlier generation Matrix blades, with inexpensive interchangeable runners, and because I wanted to be able to quickly interchange between dance, synchro and freestyle blades on the same boots. The current generation doesn't interchange, and they are fairly expensive.
The other issue is that many skate shops lack the equipment to sharpen Matrix blades - and that is also a problem with Paramount blades, last I knew.
So if you have a skate shop pro you use to sharpen your skates, you should ask that person too. If they aren't sure they can handle Matrix and/or Paramount blades, you might have to learn to sharpen your own, with appropriate tools, which is a bit of a challenge, and you (or your shop) are more likely to need to fill the old holes and drill new ones.
BTW, MK sells lightweight "MK Professional Lite"blades - but they are more expensive than standard MK Pro. E.g., I don't know if they are the cheapest source, but RainboSports sells the Lite version for $40 more.
I have never used MK Pro blades, or MK Pro Lite blades, but according to
https://www.shoprainbo.com/product/mk-professional-lite/and
https://mkblades.com/productsthey sound similar - except it says the Lite version has a thinner blade, for faster edge changes. That might make it a little harder to spin, but I'm not sure. If your skate pro, or other skaters at the rink, are knowledgeable, ask. I'm not an expert on blades, or skating.
In any event, if you use a pro shop to mount and do an initial sharpening on your blades (MK and Wilson have a reputation for needing that, though I don't know if it is still true), it will likely be cheaper in the end to order it through your pro shop, rather than through a discount mail order place.
Good luck!
EDIT: The composition of the Lite blades is a little different. I don't know the consequence. Also, I don't know if it needs any special sharpening equipment. Does anyone here have experience sharpening MK (or JW, same company) Lite blades, or know if the they look like they have a different mount for the sharpening machine?
