Exsence, Twinpower and Vanquish are all between the Stella and Sustain. The smallest size a Exsence is made in is 3000, which is the same frame as a 2500, but a deeper spool.
My#1 DS rod has a Twinpower 2500HGS. S denotes shallow spool. It holds 10 yards of backer and 50 yards of 20# braid. Any more than that and it's just a waste of line.
