Okay, as a new archer I have a question, I noticed that I managed to buy half a dozen PSE carbon force arrows that say 200 on them instead of the 300 I usually buy - probably because the pro shop manager who usually helps me wasn't there and I acutally picked something out by myself.They're already cut and everything and I shot them along wiht my 300s and can't notice a huge difference. What is the difference? Weight? Straigtness? And how SHOULD this affect arrow flight. Thanks!

The Carbon Force 200's weight 6.7 grains per inch. The Carbon Force 300's weigh 7.8 grains per inch. It is impossible to say which arrow would work better without knowing your draw length or draw weight. You may not notice a difference while shooting field tips, but you very well may notice a difference when shooting broadheads.
