Hi Glenn,
Apologies for my late reply..
I absolutely love my Stella 10000 setup with 16000 spool. I think that will stay with me forever! I haven't used the PE10 setup yet but with 100m depth, I am not sure how much difference can it make over the PE6. Either one won't overcome the initial run of a big doggie! Whereas, in deeper waters and with faster boats, the PE6 should do fine. Also the PE6 is the kinda setup you can use all the time for all type of fish. If I were you, I would just stick to the PG8K!
Nevertheless, I am still going to try the PE10 setup! It might not work but there's just 1 percent hope! And we are big suckers for hope!!
I have the Stella 20000 but still not decided on the rod. I will be going after the doggies again in January 2016.. Will keep you all posted!
Cheers
