Firstly I make my own rod tubes with plastic drainage pipe with a fixed cap one end and a screw cap the other when taking lots of rods. Taking lots of rods is more for trips I do here in this country where I may tow a boat some 10,000km often partly rough dirt roads. Some bubble wrap inside the tube stops the rough drive and rough long distance boat trips from rattling together.
Ive got various rods from one piece jigging rods, mostly Jigging Master and various multi section travel rods. The latest Shimano grappler travel rods are superb value and I have handled yellowfin to 150lb so far as well as the more common trevally and other inshore reef fish. My last trip up north was a 4300km drive each way and another 90km offshore just to reach the small remote island I based myself from. Five of us had Shimano grappler travel rods which we fished with reels ranging from Shimano Stellas's, Daiwa dogfights and Shimano Saragosa's. These outfits were fished over shallow reefs with drags set at full tension and not one broke pulling fish from shallow reef.
For a more lightweight fun outfit I also use a Bone Voyage 4 piece light spin bvs664 rod Voyage
which on that particular trip landed the biggest fish between the three boats and 15 anglers. Though this was a big fish at 2.4m in length it wasn't the most demanding by any means. The Shimano stradic 5000 with 20lb 131 braid soon had the large shovel nosed ray to the boat. I would have to say if I had to pick just one rod and reel to travel anywhere it would be the Bone as it appeals to a far wider variety of species from large to small and the rod breaks down to fit in hand luggage size. I could happily target small fish from a 200g to 50kg with that outfit as long as I didn't have to lock the drag fully.
On a tighter budget a few friends have recently been trying out the Crucis New Elite series of travel rod, which to be honest seen much the same as the Bone rod I bought a few years ago. I would certainly give one of these a try. Crucis New Elite Series Rods - Viva Fishing Australia
