Yes, Mike, there is probably alot of difference. Almost all carbon arrows weigh less than any aluminum arrow. You' ve probably picked up quite a bit of speed. I know when I shot gold tips for awhile, I could put alot more pins on my site bracket. I was shooting fairly slow heavy arrows and could only fit 5 pins on my bracket. 20-60 yards. When I put started shooting the gold tips, I had enough room on my bracket for 3 more pins, but only put on 2 more. When you start shooting at 80 yards consistently, you' d be amazed how easy a 20-30 yard shot seems. LOL
