I only used HT-100’s in the smaller Penn spinning reels and the 706 as mentioned above. There is no benefit to using Carbontex in those reels. I do use Cals grease on those washers.
On the 704 and 706 reels I still use the Penn 6-60 HT-100‘s in those reels. On 90% of them I use 2 6-60 washers and then one 6-113 washer on top. The 6-113 washer is the same size just thicker. You dont have to turn the drag knob as much to get a tighter drag.
