Stock 45 deg. vs 45 deg. aftermarket helix

Hey guys, Is there any advantage to using an aftermarket straight angle verses a stock Yamaha one? I have SLP's on my 7MM and I'm using a stock Yamaha 45 deg. now which their setup calls for. Thanks

If that's the setup you're using then yes it is to your advantage because a 45 degree helix should improve acceleration over the stock helix, which I believe is 43 in your case.

LaPorte429,Yes 43 deg. is stock on the 700MM. I switched to using a stock 45 deg. Yamaha helix that the SLP setup suggests. Just wanted to know if there was any real advantage to using an aftermarket one for any reason other than the materials. Thanks
 
Is there no opinions here? I have read here that the multi angle helixs are slightly different between manufacturers. Was just wondering about straight ones. I am now using a stock 45 and was just wondering if there was anything gained by getting a Dalton or similar 45 helix?
 
As long as we are on the subject, is the cam angle stamped on the front of the cam? Mine has a 31 stamped in it.

in my opinion, no theres no gains or losses with a stock 45 vs a aftermarket 45 if they are same angle. What your thinking of is when you compare differnt brands of multi helixs, usually they shift differnt brand to brand, and if you check the angles youll find some like to hold the intital angle longer and use a differnt radius on the helix so they shift differnt. I have checked some of the stock yamaha ones and they were just about right on straight angles. You can have a slight varaince but is not going to be anything youll notice on the tach. stock ones are cast helixs,but yamaha is pretty good about most of thier cast stuff.
