To me, the perfect HRF rod has a fast action with plenty of power in the butt section. You want a tip that is sensitive but not too fine. A tip too soft will take out a lot of the feeling as you bounce a lure back between the rocks, but one too stiff will stop you from feeling anything as well, especially with lighter lures. It all depends a little on the conditions (as always). Length too can be personal, but you don't want to go too long unless you really have to (for more reach or distance). A shorter rod will give you more leverage over a hooked fish. It'll also ensure more feeling through the rod and be lighter and easier to work with. The size of fish you're catching can come in to account too. There's no point in being prepared for a British record 100% of the time, as you'll miss out on a lot of fun along the way.
