Have been looking for a source of 'side glow' optical fibre to muck around with on my bow. Just popped into my local (sort off) archery shop and spied some optical fibre for my viper sight. Cost ?2.99 for 600mm. Wasn't until I got home and had it fitted that I noticed the receipt price was ?12.99.... ouch!... for 600mm of fibre. I have recently bought comms fibre ?4.25 for 12m. Does anyone know of a supplier of 1mm 'side glow' optical fibre in the UK. Might end up ordering from the USA.
