I still use 2pc. I have a stockpile of blades and I grab more when I see the on clearance. Craigslist, eBay, Plat it Again, etc

I once did this to my Bauer Flexlite skates to alleviate lace bite. I stuck self-adhesive closed-cell foam weather-stripping strips so they would fall on either side of the tendon. You can find different widths and thicknesses of it at hardware stores. Just make sure you choose the closed-cell foam because the open-cell stuff is not firm enough.
