my aussie is quieter than my spartan

What would you recommend for my 30? I'm gonna be hitting Rausch creek in a month or two and I want to have it in by then.

Spartan would be great. I run a synthetic oil in mine and it quietens it a good bit.

i like them both i have a aussie in my 30 and a spartan in my 8.25 they both worked amazingly this weekend at rausch, the spartan is alittle easier 2 install with the springs being in the pins and having retaining wire for the install process
