hybrid attack can't use all gpu power?

[gentl]

Hi friends.
a have 5 gpu 1080ti and hybrid attack is exellent in my case
I made wordlist with help of combipow 
So i have about 100 words
i use  hybrid attack with mask  like  

Code:

-a 6 -m 11300 hash.txt wordlist.txt -1 dig_symbols.charset ?1?1?1?1?1?1 --increment

It's rather many work to do. But hashcat running about 1 day and only 1 gpu in use with terrible speed 7-10 h/s 
Usual speed for 1 gpu is about 5000 H/s

When i use just mask attack with  ?a?a?a?a?a?a?a?a - the speed is good, but i don't need such variant.

I already read "How to create more work for full speed?"
But can't understand how i can implement this to my case. Need exact wordlist + mask.

Only one idea came to me - make wordlist with all variants  and use Straight attack.
