I have the most recent Drennan Tench rod - 13ft, two pieces with a screw-in handle. It's not a Series 7 rod - it's Drennan, with an olive green blank.
Regarding the silverfish question- yes, it will handle silver fish perfectly. Okay, it wouldn't be my first choice for trotting, or for delicate work, but for general waggler fishing, I think you'll be happy.
I use on all the time, and have never caught a tench with it
mg:. I have caught a few big roach, bream and hybrids, however, as well as countless bags of smaller fish.
It's a lovely rod.
