i can recommend this system i started using this system last season and my result were good ended up 4th highest prize winner in a strong club, i have just tweaked it a bit but is good
i fly de klak borgman direct they originate i have found them to be very reliable scoring from 70 miles to 470 miles they seem to score better when velocity is 1400 upwards even scored with them doing 2000 yds a minute
les seddon and geoff o'hare from skelmersdale probably have some of the best de klak's that i know of
