Dolphin 614 powerish handle options?

[WVHillbilly]

I want to put some kind of powerish type handle on a Dolphin 614.
Its a square 9mm hole. It appears the 615 came with a longer handle on some versions. Also searching Kencor, Immec, Compaq, and others. Appears maybe Kingfisher reels in the larger sizes may be an option as well. Considering shimano handle and remove stock to make it a bit thinner, ot modifying a Penn handle to fit as well. Thought I might ask if anyone hand such laying around or has other options to fit my needs. Thank you kindly

Daiwa has some pretty thin options on some of their Reels however you will need to do some fine tuning to square out the hole a bit . AND some of the old OCEAN CITY REELS are squared.
I got a box of various Handles I will take a look see when I can get up early enough to go to my shop and dig through it before it Melts Solder in there . Got several things to look for .
And again Welcome .

The Kencor handle is pretty nice, being orange and all. And it is more a true "power handle"
