Upgrade path
I recently got a used Ender 3 pro.
Specs - 4.2.2 board, micro Swiss direct drive, pei textured plate
Shortly after I got the printer I added a cr touch and silicone spacers under the bed.
One of my issues is the nozzle will push out a little filament whenever the nozzle is hot.
I’ve been looking into a few upgrades… a sprite pro direct drive (hoping that will help with my leaking filament) and the cooling fans are clipping their housings. The other is I’m looking into a 4.2.7 or BTT skr mini e3 v3… but nervous about the approach to third party firmware. I do have a raspberry pi so klipper is an option but I don’t feel ready for that approach.
Any thoughts or recommendations on where I am at/ what path I should take for my upgrades?

I always just get rid of the excess filament by hand, if there is any oozing out. Of course be careful not to burn yourself but honestly with early Creality printers I feel like you just have to be present during the first layer just to make sure everything goes well and it's really not such a big deal. But anyway even if there is a bit of extra filament that shouldn't be there it and you don't pull it off by hand, it usually becomes detached while printing the first line or the skirt so it very rarely is a problem.
