I would go .300,.330,.340, or .350 depending on how much weight you put up front.

350/340

 

340/350

 

I personally like a stiffer spine arrow. I would go with a 300 spine.

 

I shoot a Prime Logic 27/58... and my setup loves a 350 spine!

A tad stiff is the way to go!

Been shooting GT 400 for many years and their 5575 when that was the way they specified.
Up to you really.

 

Always go stiff. Impossible to be too stiff with a compound.

 

300 would work but is really stiff especially with a 100 grain head, 340 is great (IMO) and 400 will work as well but I wouldn't add any more up front.....your boxed in to 100 grains. If you get the 340 you can add some point weight if you want to later.

 

My experience with the SW cams on the VXR's have concluded that you would probably be Best off with 340/350 spine with maybe an additional 50gr-75gr up front. If you're not going to add point weight I would go 400 spine.
