GS-6 or GS-4 for pedalboard?

[fixit]

There is a difference in tone between GS-4 and GS-6. Any of u guys tried before. With GS-4, the sound is not full and solid. How to say ah.. i tink depth is a proper word. There is loss in the low end as well.

anyway which one u prefer? I prefer GS-6. nevermind if its thicker coz i like the sound.

space constraint-GS4 if not GS6 cause GS6 can't fit into flathead plugs.
