Thad has done some nice research it looks like.
I'd only add, if it isn't on his list, that why not just go to a big, quality name and buy a 2-piece, forget about the telescopic.
St. Croix sells them. All of the ones found on the page below with model numbers ending in a "2" are 2 piece rods. They have a 6'6" M and a MH, then I see a 7 footer in a H.
For a traveling rod, I'd be inclined to stay with one of the 6'6" models. I have a 6'6" G-Rod designed for trout and it is 2 piece, a fabulous rod. While I wouldn't go out of my way to buy a 2 piece rod except for travel convenience, once I put this G-Rod together, I forget very quickly that it is not a one piece rod.
