Opinions on rods are like opinion on cars. Depends on what your interpretation is of "light" and "casting ability". That only comes from trying out rods and seeing what best fits your liking. And yes, it does come down to what you like, not from what you read or hear about. That being said, this season I'm trying out a new rod - the Diawa Presso 7.5' UL. So far I am very pleased and it comes in a close second to my all time favorite, the Sam Heaton Super Sensitive in 7' length.
Do some research. Check out videos on YouTube. Quantify what you need and are looking for and then just buy one and try it. You can always sell it on eBay!
