It'll become obsolete before it wears out guaranteed.

Just don't abuse the cable when you're pulling it and you'll be fine.

I pulled two cables to each room/drop just in case as well.

If you're working from one box of cable, the cable has ft markings... if you pull to the furthest drop and then pre-cut all your cable based on that length (or whatever you're comfortable with) you can pull multiple wires at once... saves tons of time + you're less likely to snag/damage the first wire while pulling the second because you've already pulled both together.

I used this trick to pull 4 Cat5e + 1 RG6 wire per pull so my wire-fish only had to traverse my basement-to-attic conduit once more after the first pull. Use those wire-mesh chinese-fingertrap-type cable holders to pull that many at once.

Heh! Just saw this post. I did the whole thing myself a few years back. Some pointers.
1. The Cat 6 cabling in the attic. I made sure to run my wires UNDER the insulation as much as possible. That INSULATES it for the high temperature swings.
2. I have seen network cables run in the worst possible environments when with HP and never seen one that needed to be replaced so do not worry about it.
3. If a wire DOES break, there are ways of testing it. You can then USE one of the four spare wires that each network cable has to replace it. Just repunch.
4. Again, I have seen routers and switchers in terrible environments (enclosed racks of test equipment for instance) and did not see any higher failure rate than normal. These boxes are small and do not draw much current so they will probably handle the attic. Remember, when the boards are made they go through a 400 degree oven to run solder over the board. Heat is usually only an issue when there is no air circulation or overclocking the chips. I always told my customers that if YOU can live in the environment, then the equipment can too.
5. I was saddened to see holes in the Sheetrock just ABOVE the baseboard trim. By all means drill through the baseboard instead! Lots easier to replace the baseboard than patching and painting drywall.
6. Use closets as much as possible. Amazing that I was able to go to EVERY ROOM upstairs using only closets! I even piped all the upstairs wires from the basement via a couple of strategically placed closets on the first and 2nd floors!
Now just waiting for fiber hookups to my PC (and waiting and waiting)...

I thought gigabit uses all 4 pairs. (?)

Errr, I knew that! <bumps head against table, hard>. I am just too old is all. I still remember BNC network ring topology. Hard to remember all these new fangled devices.
I BELIEVE that if you lose a strand in a twisted pair on 1GB that it just routes around the break with a decrease in speed (which most folks would never notice). I think there is also some sort of version of 1000Base-T that uses only 2 pair but I may be wrong about that too.
Y'know, I have never bothered to TEST my cables for breaks, nicks, reflections, bad punch, etc except when I just shorted the two ends on the end plug and checked continuity. Wonder if there is a way to do this on the cheap? Geez, I was the guy that fixed the Hp/Agilent cable testers, I should be able to figure this out... To be continued..

I always recommend using Cat6 over Cat5e. Cat 6 has greater bandwidth capability than CAt5e. Cat 6 is rated for 200MHz and Cat5e for 100Mhz. Current trends show equipment transmission rates doubling about every 18 months so it is generally better to go with the cable with the highest bandwidth to 'future proof' your installation. Due to higher transmission capabilities and greater protection from external 'noise' cat6 cabling will have fewer transmission errors than Cat5e as well. I Gb's and streaming video applications perform much better over Cat6 cables. for any problem concerning your installation issues you can visit AAA All Voice and Data Inc. to get some simple solution for your DIY projects....
