Speed rating on the Q2 and Q2XL are the same. I saw a bow report in some bowhunting mag and the Q2XL actully was just a tad faster with heavier arrows. I have a Q2 and depending on what comes out this year I am planning on a Q2XL if I can find a grip that I like. Thats the one thing that I do not like about Mathews is the grip. If I cant find a grip then I will probly get a new hoyt.
