PTFE TUBE REPLACEMENT

whenever i have difficulty loading a filament on a toolhead, i usually would remove the PTFE tubing connected to TH and push it in. In my recent case i was working on TH5 and as i had difficulty loading an ASA filament, i tried to take out the PTFE tubing as i usually do and had great difficulty. Usually, pressing the "blue" part on the bowden tube would do the trick but not in this case. I ultimately was able to pull the PTFE tube out and guided the filament to load. 

I am now thinking i may need to replace the PTFE tubes on my XL. what have you guys used as a replacement.  I really like the Capricorn one's BUT seems like they only come in solid blue color so that'll be an issue, since i wouldn't be able to see a filament go through.

TIA for your kind inputs.

I replaced the PTFE tubes with Capricorn. I don't mind the blue color. Not sure it was necessary, but it couldn't hurt.

I replaced all my tubes when I bought it with 3mm id tubes, and bypassed the side sensor.  I feed directly from my drybox. 

The 3mm id tubes have much less resistance than the OE tubes.  I also run an enclosure.  Over 1800 hours of printing now and they are still in good shape.

Exactly what I have done as well (bypassed side sensors, replaced PTFE tubes with larger I.D. tubes, running a (heated) enclosure). I'm also somewhere over 1,700 hours of printing with this setup and it is working quite well (boy do I *not* miss the side sensors).
