The lineset needs to be properly sized according to the application it is being used. As long as its sized properly, shouldn't be too many effects.
Here on the beach, we have run linesets with close to 80 ft of lift.
I fully support the military and the War on Terrorism.
If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.
