Last year my 3 blade muzzies with practice blades (old blades) shot just as well as my stingers and slicktricks, too bad I lostthe sharp blades somewhere along the way- might have to pick up some new blades for this season.

Don't fret tweaking your rest in minor adjustments. Just mark where you start out and if you don't like the way things go you can always put it back at the starting point.

bitterroot- about the spine, that arrow program shows a 400 spine being way too weak for my 61# tribute, but for now they are grouping just as good if not better than my 340's (which the program puts dead on). The point of impact is off a little between the two, but when I shoot through paper at various distances it was easier to get bullet holes with the 400's. I'll let the broadheads decide when I get around to shooting them.
