I rarely use purse nets at the moment, so many small rabbits around and they are straight through them. But the dogs are making short work of them at the moment, around here the runners are referred to as 'snack packs'

The purse nets are great if there isn't many holes, any more than about three and we have the longnet out....
However several 50 yard (45metre) longnets are used pretty regularly. Unfortunately they have got to be bought from GB as no one here makes them here

The cheapest way is to buy a net unrigged then put it together here, time consuming and fiddly but way cheaper than buying ready to go. Its the freight that really kills it. I prefer several 50 yard nets to a lesser number of 100 yard (90 metre) nets, those 100s get heavy by the end of the day.
When buying longnets go for 50 yard with 100% bag. What that means is the net is actually 100 but you 'shorten' it up, this is what tangles the rabbit and keeps it caught. I've got some with 50% bag but find they just don't catch that well.
