So this is essentially Minecraft's Buildcraft mod, minus the machines and power system. Which is fine, because having to convert between BC and IC power was a hassle anyway.
As useful as this mod is, it does have its shortcomings:
Accelerator tubes are rather expensive, requiring 8 iron, 4 copper, and 19-ish plastic sheets (although you get those back) (assuming I did my math right) each.
High-priority tubes, while supposedly a low-cpu alternative to using filter tubes for directing things, don't actually do anything as far as I can tell. Items will exit them even in directions that aren't visually connected to adjacent tubes. Maybe I'm doing it wrong, but there aren't any directions for them as far as I can tell.
One-way tubes only connect on their fronts and backs. This means that while they do have their uses, if one wants to replicate the function of Buildcraft's iron tubes (which accept items from all directions but only output them in one), one's only option is filter tubes.
Tubes overall seem to cause quite a bit of lag when used en masse, with items continuing past pipe corners before getting rubber-banded back in. This even happens in singleplayer.
Sometimes, the visible connections on tubes don't get updated like they should. The most common case for this is when connecting one-way tubes. An easy fix for this would be to have pipes re-check their connections when hit with a screwdriver.
As for the good:
Filter pipes are much less expensive than in BC, costing a tube segment and 4 mese shards, versus BC's cost of 1 glass and 2 diamonds. This is good, since you'll be using them a lot on account of the issues mentioned in the previous section.
Teleport pipes. That's it.
No engines needed for item extraction/output.
This mod isn't without its flaws, but you need to have it if you use technic (or just want to do any sort of automatic item transport.
