Maver 131, it's 13m (13.5 with butt piece), bit bendier than I think it should be but I dont have a lot of experience of other poles to compare it against. Had a Maver genesis before and I ain't convinced the 131 is a lot better, might be at longer lengths.
Try as many as you can side by side. At the longer lengths the weight of the elastic seems to make a difference.
I do use mine at it's full 13m but it is much better at 10m.
I do like having a range of top kits, I got 6,10,14,16 and 20 elastics.
