Excellent review.. Thx for adding the 736 in there. From what I've recently be told the 734 is a great all around rod. Although it's rated at a heavy power and the 735 is a Medium Heavy here's how they stack up. The 734 In the 4 power world according to Dobyns it is a heavy.. When you step up to a 5 power things change.. So, in the 5 power world the 735 becomes a medium heavy. The word medium can be confusing but in this case the 5 tells you it's still a heavier action rod than a 4.
That being said the 5 would be a much better rod for working in heavy cover... The 6 possibly better depending on just how heavy.
As for casting the 5 will be very accommodating with a half oz bait. I'd be interested in knowing how the 6 tip would react to the same bait weight being thrown,. if its got some life I'm a buyer. I'd probably pass on the 735..
DTack made some great points I'm pleased to hear and agree with. He obviously knows the Dobyns rods. Now where getting somewhere... at least with a few of the Dobyns Rods.
