Just incase anyones interested, I own several sets of shs gears, 13.1,18.1 and 100:300. All sets work great and with a proper shim job are very quite indeed. The 13:1 gears are silent but not much good for anything over a m100. The 18:1 are great, i've put about 10k rounds through with a PDI 150% and the are still perfect. The 100:300 are triple torque helicals, they are very hard to shim right but when you get it they are pretty good. They will pull a m150 like its not even there. They work very well with an 11.1v li-po, I get around 19-20rps, pretty much the same as the standard ratio gears(18.1) with a 9.6v ni-mh. I've had element gears as well and I can tell you that they are nothing like the shs gears, they are crap, even with perfect shimming they are loud but I've never broken a set yet so take that as you will. I've broken my original G&G gears(500rounds), my classic army set(5K) but the shs are still going strong, very nice gears in my opinion, I've never owned any high end gears so I can't compaire
