LBR - I am going to show you a way to get 20% better gas mileage out of your vehicle. Are you interested ? Why ? Would like to get that additional performance ? The differnce between 20 mpg and 24 mpg over the course of 50,000 miles and $4 a gallon gas matters, doesn't it ?

OL gets that kind of % increase in bow performance. Ashby's results (have you read them?) shows clearly that using FOC arrows, slick arrows, 2 blade single heads etc etc all get you little bits that ends up being a nice bit of additional performance.

Its the differnce between 6" of penetration and 14" inches - the difference might very well be a dead buck vs a wounded and lost one.

I think it matters.
