Which is why I put my EnderIO redstone conduits in the same block space as my other EnderIO conduits, and cover it all up with EnderIO facades. EnderIO redstone conduits also have color channels that work almost identical to the bundled cables. As for the logic gates, Engineer's Toolbox is more flexible. It has most of the usual circuits and you can program the side where the output(s) go(es), and you can cover it all up with Buildcraft facades. And if that isn't enough, there's always the programmable RedNet controller.
I'm beginning to think that using familiar mods too much might make you reluctant to look over the fence.
(I do circle back on-topic here)
I'll admit I haven't yet tried engineers toolbox or even enderIO (though I've been meaning to), mostly because a lot of the functionality they offer, I already have in other mods that I play, and partly because a few of the 'new' mods I have wanted to try haven't updated yet, putting off any updates until everything is ready.
But I was also thrown off engineers toolbox because the instant I looked at it, it just looked horrible (to me). everything is a block, block block block, there's no wire aesthetic, no cable - just blocks, ugh.... And, not to be offensive, but the textures seem a little... strong.
There's an elegance and beauty in the wires in RP, and now P:R. They look neat, and a well setup system is a wonder to behold. Furthermore, you can walk through the cables - which is SO nice in a confined space, something a lot of other wire systems are missing.
The other reason P:R cables are so nice to have is because of their simplicity, they're incredibly easy to use for small systems all the way up to complicated multi-bundle builds, they're easy to understand and setup for any tier.
I don't know if the same is true for ender IO, or engineers toolbox, or any of the other mods that can replace the bare functionality of P:R cables, but I haven't seen any yet that offer the same benefits, being able to walk through them, the slim-cable aesthetic (or something better?), FMP, simplicity and usefulness from naught to eleven, and neatness - to me at least, these things outweigh the over-compactability and customisability of other solutions.
And that's why I haven't switched, and don't want to. Because I don't
need to, P:R cables are just plain awesome, and I'd be extremely sad if they went away. Sure, I'd get by, but my builds would never look or feel the same. Especially since I have no intention of ever using RP3 unless Elo adds something truly wonderous (which is a possibility), but even then, I'd probably still have P:R for the logic/wires, and FMP for microblocks, just because I can.
I like the way my redstone looks and feels with P:R, I don't mind if it takes up a little more room than alternative mods, or I have to use three gates just to route a wire around. I just want to keep my wires.
Edit: To clarify, this is me, you're obviously free to use whatever you want, but I'm tyring to point out that just because alternatives are out there, that doesn't mean P:R wouldn't be missed if it were dropped, and I'm sure more than a few people agree with me that it should continue, should the mod dev be willing, ofcourse - which they currently are.
