If you shoot the bird early enough with maintained then line doesnt come in to the equation, thats prob why people who shoot maintained lead also shoot pretty quick
As ive already said pick up point is vital, i used to struggle alot with teal targets but shooting maintained lead turns them in to relatve bag fillers
where you have to be careful is on long slow crossers, anything under power is no problem
Im not saying the other methods are wrong, just as maintained isn't wrong in the right hands
Maybe i shoot start this Fitasc lark, might start a new trend?
