I used a saltist 6500 in Fiji at Christmas time, landed a 17kg gt but broke the handle shaft on the main gear in the process. I continued to use the reel for another week, just had to make sure the side screw was tightened, in fact I only found out it was broken when I removed the handle for some reason. I was using 80lb braid and a very stiff drag. Daiwa replaced it on the spot when I returned.
I've landed a heap of kings to 85cm since without an issue.
I'd use the reel again on a future trip but limit it to 60lb line.
Just my limited opinion, others will vastly disagree.
