RE: Chrono'd the Switchback today...
Mowtown , I think you arrow weight is wrong , you should be at around 400 grains with a 29 inch 349 ,vanes ,and 100grain tips . The reason I responded is that is the arrow I shoot but with vanes, and Im at 375 grains .

ORIGINAL: TerryM He is shooting blazers which are quite light compared to most vanes. He could be shaving 10-15 grains easily with those vanes. Blazers weigh about 9 grains less for 3 compared to AAE/Duras, BTW |

See Signature for Bowtech Allegiance stats.

RE: Chrono'd the Switchback today...
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.
|
RE: Chrono'd the Switchback today...
Jeff are those blazers that much lighter where you can get app. 20 fps faster with your switchback?
|
RE: Chrono'd the Switchback today...
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...
|
RE: Chrono'd the Switchback today...
26" that explains it , are you shooting an overdraw ?
|
RE: Chrono'd the Switchback today...
Nope a drop away with the arrow just clearing the prongs

RE: Chrono'd the Switchback today...

ORIGINAL: MOTOWNHONKEY Jeff are those blazers that much lighter where you can get app. 20 fps faster with your switchback? 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? |
RE: Chrono'd the Switchback today...
Heh..nope...:D 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? [/quote] 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 |
RE: Chrono'd the Switchback today...
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.

RE: Chrono'd the Switchback today...
Actually it really *is* cam timing.
Problem is mostdumbass bowshop workersstarted using the incorrect term of "timing" when they meant "synchronization", years and years ago..... Look up the AMO/ATA definition. *All*cam systems have to be timed..One cams have nothing to be *synchronized* with (no other cam) and that was thier claim to fame. You'll notice Mathews always uses the correct term of "synch" in their marketing. Most other companies do not, either out of ignorance, or because they don't want to confuse people becausethe masses areonly familiar with the incorrect terminology (propogated by said people who don't know the correct terminology) Sorry, but this has always been a pet peeve of mine...nothin personal :D |
