RE: Question about new arrows and correct spine..
Yeh, people know. They are at work. Anyway, I'd shoot the 60-75. 45-60 is way underspined for your setup. That being said, I don't know why you want to shoot the Terminators. They are only marginally lighter than what you have. You are apparently looking for some more speed. It's easy to get it, but you'll have to buy better quality shafts, like Carbon Express CX or 3D Selects. The Terminators are only going to give you about 8-10fps more, and you probably won't even see it at anything under 35 yards.
There is one way to gain a ton of speed in most setups. That is to get rid of as much weight on the string as you can. Brass nocksets cost 4fps for each one. A kisser button is another 5fps. Peep tubes is another 3-5fps. Cut down the length of your center serving. about 3" is all you need. If it's the normal 7" or so you're losing another 4-5fps. Keep string silencers as close to the cam as possible. The closer everything is to the center of the string the slower your bow will be. It's very easy to rob your bow of up to 20-25fps just because of the junk on the string and it's location.
Remember, too, that all this is going to make your bow a bit noisier. If it's for hunting you have to decide whether you want speed or quiet OR try to reach a compromise between the two.
