difference between sq and s trim?

[tarpymac]

are they the same thing? is the sq the same as the s trim? does the sq just stand to make it more quiet?

S-trim has straight cut gears(loud) SQ has helical cut gears(quiet)and has a different step up ratio designed to come in a little sooner, not really much of a difference, but sound factor is the difference. I have the SQ and with the hood shut it's barely heard :D (stealth) I like it like that.
