If I could get my hands on an old SSB 136 3M, I would take it over a 121 3M. The SSB was my go-to beach spinning rod for a lot of years, from the mid-1980s almost until the turn of the century (remember when that term referred to the changeover from the 19th to the 20th?).
For eels, I would probably take all the trimming from the butt.
But in a perfect world with a bigger budget, I would take an XRA 1205 over any glass rod.
