I own two black max casting reels and am looking to find aftermarket reel handles to replace the stock ones currently on it.

The stock handles are practically brand new on the black max reels, however since using my Shimano SLX and Curado reels I've obtained a strong preference for the size and feel of the Shimano reel handles. 

Does anyone know of a reel handle that would give me the Shimano feel I'm after?

Perhaps I could simply buy a Shimano reel handle and install it on the black max? Forgive my ignorance, I'm not an expert on reels.

 

Thanks!!!

Shimano reel handles have a different size (7 x 4) mount than that of Abu and Daiwa (8 x 5) so they won't work.  Your best bet is something like a Gomexus carbon fiber handle.  You can find them on Amazon, eBay, and AliExpress.  

In addition to handles to swap, SDS Custom on ebay offers some nice EVA knobs

that will swap onto your handle.

If you want to go the handle swap route:

You need 8x5 mm rectangular slot to fit Daiwa and Abu.  7x4 mm fits Shimano.  

 

Especially if you go to Ali Express, look at the carbon handle by ArtSea - rubber paddles

and this one has shaped cork knobs

 

This Fluke handle has oversized cork knobs - they have the Daiwa/Abu 8x5 in black.  

 

Gomexus has a website -easier to see what they offer and just as easy to buy.

The good Japan handles almost cost a reel, but they're very nice with titanium hardware, etc.  

My favorite Avail handle - JapanTackle, Hedgehog Studio to find these.  

 

this is Studio Composite carbon handle - if you think it looks strange, it's even nicer to fish than it looks strange.  Best place to buy this one is FishingShopKiwi.
