Love the dual chutes. I run about the same combo altered. Only been over 200mph once, but still like the dual simpsons 10' I think. With an altered, keepin it under control on the shut down is just as hard or harder than keepin it in the groove. I have 2 levers side by side. tall 1 for 1 chute. the close 1 gives you both. works great.
