I like tripods, which seem to be going the way of the dodo for modern photography. I have what's probably the same tripod you have (Bogen 3020--about 7-8 pounds with head) which I've had since 1982 or so. Of course I have others, lots of others. Depending on your needs and budget, I'd recommend looking at a carbon fiber tripod. For the same diameter (which relates to stiffness), carbon fiber is much stiffer than aluminum, which means you can use a smaller carbon tripod. Although I have an expensive Gitzo CF tripod for my big lenses, other brands, such as Benro, Siriu, etc. have decent stuff (I use a Benro ball head). My daily use tripod, which replaced my Bogen, is a three section Velbon CF which isn't made any more (and which I take canoeing when photos are important--works fine for up to 400mm lenses, with care). I just found the replacement, link below. This might help in evaluating where to go in relation to your current Bogen. It is more compact, stiffer, and much nicer (warmer, quieter) to use than the Bogen, and is 3 pounds lighter. You might try used, too--I bought my Gitzo CF off B&H used section, and saved probably $300. I recently saw a smaller used Gitzo at a shop for $200, about $300 below new.
