You don't even need wire pulls, you can just push cat5 through 3/4 ENT tubes and expect it to pop out the other side.

Smurf tubes are great, but plugs like on Cat5 or HDMI cables get easily hung up while pulling cables. The ones you link above look smoother than the ones I've had the (dis)pleasure of working with, which were ribbed, making snags frequent & annoying, especially at any sort of 90 degree bend. It's still significantly easier (and safer) than blind runs through walls.

  At least for cat5/6, wouldn't you be cutting and terminating once they're pulled? Never thought about pulling one of those with the connector on - for the reason you mentioned, but also just because you might not know how much cable you'll need until it's all finished. I'd imagine HDMI would be mostly shorter runs (or using cat5/6 extenders) due to the limits/requirements of the cable.

Sounds like you have done this before... quick question: is it normal to run multiple conduits carrying the same type of cable parallel to each other? For instance, multiple conduits running up from the first floor to the attic where all the final runs are done. It seems like 2" smurf tubes are relatively rare (I can find them but seems like they aren't interested in selling them in 100 foot rolls) so 1" are more common. According to conduit guidelines, 1" conduit for 40% Cat6 is a measly 6 cables while 2" is 22. So even at 2", I would still need 2 - 3 two-inch conduit runs. Is this off-base or do people generally hunt down 2"+ conduit?

  I didn't have that situation (I was putting in Smurf tubes while insulating an old balloon-framed house, so I was mostly doing straight runs down the walls, with the occasional bend around a window, before filling up the airspaces), but if I did, I'd try to just build a void in to go all the way up to the attic. If you don't want to leave it bare wood, you could put in 4" PVC, with the T's at each floor, instead.

    Hmm! Thanks for the input. I was considering PVC as well. My house is old and had multiple additions so its layout is all topsy turvy and there are no straight cavities so I might just run lots of flexible conduit at least up from the server closet into the attic. At least then it will be a little easier to run new drops.
