what MSD should I use

[pegasus]

I have a AL6 and a A6

also i have a blaster 2 and a blaster ss

[kennebellcobra]

The only difference is a 6al has a rev limiter the 6a does not. I would go with a digital-6 plus though.

[Silver Bullet]

I agree with the above.... at least go with a digital box.....
