I had to google t-wing
this sounds good, like something I would want?
T-WING SYSTEM (TWS™)
The T-Wing System of DAIWA solves an age old problem with baitcasting reel levelwind systems.
The "T" aperture allows line to flow freely through the wide top section on outcast, reducing the normally sharp angles, and friction that slow line flowing through a narrow aperture when exiting the reel.
For retrieve line drops in the narrow, lower channel of the "T-Wing" for even distribution across the spool width.
