XTD
-Waterproof drag: No
-Maintenance port Yes
Ci4
-Waterproofdrag: Yes
- maintenance port: No
The Xtd has felt washers, because it is not waterproof it can get stuck after a while (solution other washers)
Carbon/Ice will give a very fast drag 3/4, Teflon will make it 1,1.5 turn, no idea about C-t/Pom washers
Ci4 already have good washers no need to replace them if you dont need a super fast drag.
From Shimano for reels with Maintenance port:
MAINTENANCE BEFORE FISHING
Always ensure your self that your reel is running well by moving the handle and check if your drag is working properly. Ensure yourself that all moving function are working properly. For reels with maintenance port we advise to put one drop (only 1 drop) of Shimano Bantam oil in the maintenance port every 2 times you go fishing.
