Hoh,
Ive used all the rods you mentioned, I personall recomend the HSR 1025C. Its stiff enough to bacbounce with and handles k-15 and k -16 kwikfish great.
If you just want a backbouncer stick with the shorter 1 piece rod. I know they can be a pain in the butt to store and transport but, they are the ultimate backbouncer.
The SAR 1084 is too long and doesnt have the backbone for bouncing. The HSR 1023 has too light of a tip for heaey leads.
Hope this helps
