I have some but they remain unused. I do use Polaris floats though regularly snd prefer the old original ones to the new. I have at least 12 of different types.
Funnily enough I have just bought some more of these . I use them on the Severn float legering for perch , i use a bobber float or a decent sized loafer float . They work really well and give you the flexibility to use any float as a polaris type .
