Scorpion thumb safety help

[tk4]

Recently picked up a Scorpion.  I have short thumbs.  I put a Magpul grip on it and replaced the stock thumb safeties with the long PMM thumb safeties.   The PMMs are still a little too short for me to flip them reliably.   

The AK reverse safety doesn't seem like a good option due to the fact that the trigger finger would be moving away from the trigger when it should be getting on the trigger.

Any recommendations???

Thanks

Have you tried the HBI Long pictured here:  https://www.rainierarms.com/blog/aftermarket-safeties-for-the-cz-scorpion-evo3/

I may have to try it if there isn't a longer thumb option.  

Just doesn't make sense to give the trigger finger two jobs in opposing directions when trying to be fast and accurate on the first shot.
