I love my FOBs! They are right, once you go FOB you will never look back. I shoot G5 Expert II rest on both of my bows.

I also shoot FOB's! They are everything you read on Starrflight.com and then some!! You pick any broadhead you want to shoot and it will fly! They were designed to guide large fixed blade heads. Paul (the designer) is a rocket engineer, so I would put money down that he knows a little about fast flying objects!!

I have smashed broadheads between big rocks--taken off blades...and just about anything you could imagine to try and throw them off and they still hit the X!

I tried the and did not like them. I shot awesome groups with them and were starting to cost money because I kept breaking them. Then I put the slick tricks on them. 20 yrds grouped with field points, 30 yrds again grouped with field points. At 40 yrds there was about a 12 inch drop. WTF. So I fletched 3 arrows with blazers and shot those with my slick tricks. Grouped with the field points. Even at 50 yards they still grouped with the field points. Needless to say I decided not to go with FOBS. I also thought they were too loud in flight. Not for everyone. They were fun to shoot though.

The Fob's seem loud because of the air decompressing and is all in the rear. There have been a lot of research done on this.
As far as your drop at 40..you got me. I am just fine out to 70. I would guess it is your arrow and FOC or bow tune... Not busting your chops, just guessing. I am shooting 437 grain arrow @ 296.

Seems like a wonderful invention for the country club hunters.

I probably save some money, doing it the old way with vanes.

If you want to give them a try send me a pm! I have a few test kits laying around!

Can someone tell me how wide they are? Im shooting a 101st and its sometimes tough to get clearance.(Its tough with blazers anyway) I wouldnt mind trying them, but i would rather know they work before buying some.

They are just shy of 3 Blazer's on a standard size arrow..1 116" I believe....don't quote me though

they are actually cheaper. lol

I like the FOB. It makes a little noise as it cuts the wind, but nothing to worry about. I was shooting it off a New Breed Nemesis with the new QAD drop away rest. The arrow flew great. I took some long shots across the wind and had great arrow flight. Neat product.
