I tried to edit it so everything lined up, but it didn't work.Here is a pole float size conversion chart,upto 0.50g
pole float size .. weight .. shot equivalent..
3x10 0.10g 2 x No 10
4x10 0.15g 3 x No 9
4x12 0.20g 5 x No 10
4x14 0.40g 6 x No 8
4x16 0.50g 8 x No 8
the above can be mixed between No 8 , 9 , 10 shot/stotz depending on shotting pattern,
anything above 0.50g I think is better using a small olivette and shot/stotz.
Yes, but you don't have to take that as gospel, I have used lighter floats in deep water also heavy floats in the margins to minimize your line and bait being wafted around if you get a couple of decent fish in your swim. I try to fish as light as possible depending on weather conditions etc.
