Yes, and it probably is from your whisker bicuit. you are barking up the right tree by considering blazers, they hold up better through a WB.

As archer explained, 250 is the arbitrary number assigned to that particular model of arrow to reflect a deflection of .390.

yes you can. In fact, there are several good choices that don't require anything more than a pot of hot water to adhere new vanes to your shafts. Quickfletch (by NAP) and extreme archery both have products that will suit your needs. You can if you choose purchase a fletching jig, but thats a more complicated deal.

Honestly I can't say. There is so little information given about them. You need to know what spine/stiffness you'll need. What # are you shooting, what is your draw length? That company selling those arrows doesn't know the difference between the model and maker of the arrows, I would consider purchasing arrows through a reputable dealer. If you select the wrong spine of arrow, you can have pretty poor flight and results. In extreme cases of too weak a spine, you could even put an arrow through your arm... I say this because this ALMOST happened to me when I was young and dumb and bought arrows at wal-mart. (I shot 30-50 thunderstorms arrows at 28" off my hoyt ultra tec at 29.5" draw and 73#s... I killed 6 deer with one of those things... and never had it break... I got extremely lucky.... they sure were fast though.....
