The LT4 poles have a lot of neat secrets. One that I noticed and never see referred to is that you can actually combine the two poles with NO added parts into a single pole that goes up to 80". That's right, you can pitch enormous pyramids like the MLD SuperMid with just a regular pair of LT4's.
To do this, pop the small cap off one of the handles and pop the little piece of tape that's underneath too so you have access to the upper end of the carbon tube. Now you can simply grab the lower section of the other pole and screw it into the top of this pole. Even if you don't need a super tall pole, this is a nice way to pitch any pyramid in rough weather because at 50-60" almost the entire thing is doubled up, so the pole is significantly stronger than a single pole extended to the max.
The downsides are (1) you've got tips at both ends, so if your shelter doesn't have a grommet at the peak for the pole tip, you'll need some sort of protection for the tent. Bringing along a metal shot glass would be good and could be multi-use :). I normally use a single pole with my DuoMid, but if I really hit rough weather I'd use both like this and toss my metal cup over the upper tip. The second downside is that with the cap removed from one of the pole handles, if you're hiking in extended wet conditions you do get some water in the pole which makes it more prone to slipping. The upside though, is that you don't get the air/pressure lock inside the poles that makes them tough to adjust in length.
