How do you mitigate splash damage vs. blaziers

I wouldn't normally post this and I try to read as much as I can but at the moment I'm kindof stuck and yes I know there were quite a few post about splash damage already. How heres my question and if I misunderstood something I read tell me. If I can't afford to put up blaziers because it takes 5 tiles across plus whatever land I want to protect with a claim. That would be wall -tile space wall tile space and wall then blazer because you cant stack walls when using blazers and it all has to be on claimed land, how many or what kind of walls do i put up...as many as I can make? Would it be splitrail, stone,splitrail, stone and so on to soak up the splash damage...would six layers be enough to deter someone from raiding my place? Can you put up 3 spaced walls and just run a claim line around it so the blazers work? And to clarify I can't just have one claimed wall and blazers right...Thanks ahead of time guys.
