Could any users of the newer cabrinha trimlite with the grey mainline tube comment on whether they leech gunk/grease like the black ones when used? My 2017 seems to be getting worse & looking at replacing the tube only.

Not sure what's causing it but it's been mentioned a few times in various forums. Clean it before every session & wash the sand off after launching but reappears within 20 mins. Stopped wearing sunscreen for a bit in case that was the culprit but made no difference. Cheers.
