I have one of these laying around. Was perusing ebay for a set of carbontex drag washers and these pop up:

Any experience with these? Besides this, are there any other options for a BFS spool on this? Thank you.

@redmeansdistortion needs to answer this question for you.  

I don't know enough about the sizing of these reels, but he loves to bench-race them. 

He has mentioned they share many Alphas/Pixy parts.  

 

I can answer about Roro spool for Daiwa SV reel - I've fished two very similar 34-mm Roro-X spools on Steez and Silver Wolf.  

Fixed-inductor spools like Roro-X and AMO change magforce into linear mag brake.  That's all you need casting 1/4 oz (7 g) and lighter. Because of the extreme light weight (low inertia), they cast the lightest weights (1/16 oz) farther than any other spool option.  They are unforgiving of start-up jerk casting heavy weights or with wrist snap.  I pick these spools for fine braid (PE#1 and smaller) and fishing 2 or 3 g.  

 

 

You should be able to fit a current Daiwa BFS spool or a Ray's Studio moving-inductor spool -   - that's where we need @redmeansdistortion to answer.  

The moving inductor spools are literally twice as heavy, let you fish a wider weight range, and the Daiwa versions will let you fish mono.  (these examples are 34-mm, and won't fit your reel)

These trade light end distance for improved cast reliability, and where I use them is fishing PE#1 and larger, generally casting 1/8 oz (4 to 6 g), but these will keep on fishing up to a full ounce.  

You can use any of the many 34mm 103 sized spools you see being used in the old Steez TD-Z 103 ect but you will need the plastic T shaped shaft under the spool tension knob swapped out with a slightly shorter one from an Alphas or similar reel.

thank you. Last time I changed spools on a reel was with an abu 4600cb into the avail micro cast. Love that reel but I ended up bending one of the brake spokes(?). 
 

I think 5g would be a good middle weight for me. I fish in jettys mostly and this will be with braid. I have a Yamaga blue current 78b that I am waiting to be delivered. Don’t know if I will pair that with my Brenious, but what I really want is a lighter spool for this millionaire I have.

Thank you, I will check out what that shaft is.

That will nail it - my Steez currently with AMO spool and PE#0.8 is matched with Y/B BCIII 82/B - the lightweight rod loves the light weight of the Steez BFS-mod, and I mostly fish 3-g microplugs with plug hook swaps
