Hi Dan.
Have been using the Ultimo 82 MH recently with a very similar setup ,Stella 10k / SOM 16k spool and JB 80 hollow. Main lures have been Siren 250 and Heru Ulua 150 which end up about 170g rigged , and it has performed flawlessly so far on fish to 35 kg on some reasonably shallow reefs, with some power in reserve. The 7'9 should have even more, but have yet to attach to a monster to really test it.
I changed from a carpenter TBL 80/40 to the lighter outfit and personally seem to get a better action out of stickbaits with the Ultimo.
For the lure range and setup you mention the 7'9 should fit the bill perfectly for stickbaits, haven't thrown any poppers with it but as a pure stick rod I can't fault it.
Hope this helps .
Cheers Rob
