Replacing LM6LUU head bearings to Igus RJZM_01_06

Since my um2 tests on umo+ I been wondering about changing the linear bearings of the hotend to Igus. Since they don't 'roll' and just slide it should remove sound on the hotend and ringing since they are shock absorb and also, and very important, they cost 3€ each.
Other interesting think to do could be to change the Linear bearings of the Z bed from the square flanged ones to FJUMT_02_12. That it's almost an instant replacement, but they cost 37€ each... Soooo not on my soon to-do since I already have the cost effective misumi and they are quite fantastic.
Some random video I found about igus vs a linear bearing
So I'm doing this with the um2 hotend, I think it will be a pain to print since my skills on that department are meh, but seem's the basic stuff it's done. Ofc I left room for the bowden to go in without hitting stuff. As soon my order from igus arrives and I print this I'll post print tests of before and after at 5000 aceleration to see the maximum ringing posible and if it affects or it doesn't.
