Some of the newer hollow and hydro elastics are a bit thicker than solid but they stretch forever so, if you are deliberately fishing for silvers and bream and you hook a lump you have a better chance of getting it out. Of course, having a side-puller greatly improves your chances. I am shortly going to elasticate a Match top 3 for the winter and, although I really like Daiwa Hydro there are other hollow elastics on the market at half the price, Preston, J Range and a new Middy Hi-Viz Shock Core. Oh, and the new Daiwa Hydro Yellow, which is lighter than pink and blue.
Interestingly Middy specify an optimum fish-weight range for their hollow elastics - the green being for fish up to 3lb.
