Here here let me settle this here debate. 26 and 3/4 arrows 71 # limbs. 4 inch dura vanes. Unless my meter is off the arrow weight is as posted.

Jeff are those blazers that much lighter where you can get app. 20 fps faster with your switchback?

MOTOWN, when I went from duravanes to blazers I picked up +/- 5 fps, some of which was due to the reduction in weight and some was due to less friction with the biscuit...

26" that explains it , are you shooting an overdraw ?

Nope a drop away with the arrow just clearing the prongs

Tried my viper tec the other day. DL 27 1/2
64lbs
324 grs
string loop
273 fps

Heh..nope...

your bow is def slow...I've shot 3 diff 28.5's and they all were within a couple FPS of each other...you DO have to get that cam tining dead on on SB to get the speed, 10 FPS if the cam is outta whack wouldn;'t surprise me...but, you should be shooting close to 300 w/ that light of an arrow...And I assume you have the limbs maxed?

How do you adjust the cam timing on a Switchback? I thought that wasn't an issue on a single cam bow. Little do I know, and I own a Switchback. How much do the string leeches slow down the arrow?
Thanks

Its not really cam timing....It's more like cam orientation. It's not as critical as keeping the ATA and the Brace height in spec. Depending on which way the cam is off you need to put some twist in the cable or string.
