Got both Zillion 100 HA and SHA for ripping rattletraps. What do you guys prefer? I’m running 50 lb braid for grass/weeds, but the HA (6.3:1) feels a little slow and am using 12lbs Yo-Zuri hybrid line. Thinking about switching it up line to 50lbs . Also have a Crazy Crank (4.9:1) for chatterbaits to crawl them along the bottom.

 

Is there anywhere to grab gear sets to bump these up to 7.1:1? Checked TackleTrap but they’re out. Any other sources?

6.3:1 should be fine.  It's a 36mm spool reel.  That brings up the IPT compared to a similar ratio 34 mm or 32 mm reel.  I can keep a buzzbait on top with my 6.5:1 36m spool reels easily.  Are you actually finding the reel too slow or is the ratio getting into your head?  You can aways do an IPT test or do what I do and "can it fish a buzzbait comfortably" test.

I don’t think the difference between 6.3 and 7.1 is enough to justify the expense of a swap. I’ll do whatever a customer wants, but is asked for advice I don’t recommend gear swaps unless the reel is not available in a particular ratio.  

If you want to make it a burner you can do the 7.9 swap.  The SV 103 is a TD Zillion.

I tried it again with braided line (40 lb Sufix 832 Ghost), and it worked much better for me. I was able to maintain control and pull rattletrap out of the grass much more easily. I think I’ll stick with this setup for now. 

Taking virtually all the stretch out of the equation is world of difference.  I was going to get rid of a MH MF I had because it felt too soft and slow for pitching and didn't have enough power in the mid-section for chatterbaits.  When I use a reel with braid, it's like a different rod.
