Reeds, which is better?

well it seems i may have a reed problem. atleast one of my friends thinks so. my blaster idles, give it gas then climbs down. then give it gas again and it stays up for a few second (about 5) then climbs down. i know it might be a needle slide problem just asking if anyone might know?
 
I got some nice tech 7's for christmas, I love alpinestars boots. But to be honest they are a bit more important than vf4's ;)

I wanna get some vf4's (or 3's) to compliment my KOR work but they are just too darn expensive.

Stormtrooper boots heheI:I
