getting value in bet365 isn't that hard for the obscure leagues , have you checked the tipsters in blogabet ? pretty much all of them use bet365 and there are many who have over 15% yield
you can use the filters there as well and  filter the tipsters who are using mainly bet365 , but you won't need that cause the majority are using it for their picks anyways

for the popular tipsters tho you need to be very fast cause odds drop within a minute sometimes , but the majority of the services are fine and you can bet with their odds if you catch the pick when they send it
