Yeah i think so, the 16 i'm sure of, the 18 not really.. Remember, i just casted the rods i didn't really like the looks of them, so i'm guessing really

.. Do you like to fish thumb on top?? If not you might want to reconsider, i didn't really like the feel when my index finger was on top but then again my hands are, well strange

.. But i'm thinking because it's a ten footer for a six you will probably cast thumb on top..
The guy who build the rods used forecast woven graphite seats but i'm not familiar with those seats.. I do remember there was just a very thin layer on top of the butt ring (very funny indeed

but thats what they are called i guess

).. I will have a look if i can find the seats some where on the net.. So i can give you a better idea of how thick the lower end is..
