Brake pipe routes

[NeilW]

Hi guys,
Just about to start installing the brake pipes, having read through some other builds I see several methods of installation but I am a bit stuck on how many pipes I should run through the trans tunnel. I was planning individual pipes to both front wheel, one pipe from front to back with a 'tee' to split to rear wheels.
Is there any concerns to run the tee split at the rear as opposed to the front?
