I’m currently testing a range of cane tipped silverfish floats made in a more traditional way with tip and stem material meeting in the middle of the float body, this gives the float good balance and is still proving to be very durable as they are put together with strong glue and a hard coating.
I have been using them for about 3 months on skimmer dominated venues with some roach and carp mixed in, catching good weights with many in the 30-60lb range and have not managed to break one yet!
They will be listed in the shop soon, some photos can be seen here.
