27.5 and a loop is perfect, it feels great.

My CR337 at 28'' seems to be shooter. My arrow is almost to the rest on my cardiac, but on my CR337 I have 1'' over hanging.

Anyone know why? Weird[&:]

Depthof the risermaybe?

YOu know

1 has an 7 3/4 Bh and they other 7'' BH is that it?

I think so. I was looking at both pictures and the front of the riser is shallower on the CR337 (at least to my eye). That and the 3/4" difference in brace height would probably be the reason why the arrow looks so much different at full draw depending on bow.

That was my first thought when I read the first post - Brace Height

Damn I am going to need longer arrows[:@]

I'm not sure either, but I know a 30" DL on one bow may be different on another. My Vectrix Plus is a 30" draw, and it's perfect. BUT, we have a couple Cardiacs in the shop ( [:@]) and a 30 is too long. A 29 1/2 is perfect. Don't ask me, I don't know.

The brace shouldn't make a difference but it is possble that the specs on 1 bow could be off or the mounting hole could be different.In relation to where you grip the bow.

Is it the same rest?

Maybe where the rest is mounted on the bow? DL isn't measured from the string to the rest is it?

DL is measured from the nock to the curve in the grip +1.75" at full draw. This is why I can't figure out how 2 different bows that are have 30" DL could be different. It's not rocket science. Do bow manufacturers hire 6 yr olds to measure?
