I've been shooting the HortonCarbon Strike MXwith good results. The Carbon Expresses look decent too. The only reason I bought the Hortons is because you can get a half dozen at Walmart.com for like $36 shipped! Or you can have them sent to your local Wally World freeand pick 'em up. for only $30 The only thing is they have 4" vanes. Here is the link if anyone wants to check them out:

I've seen them for up to twice as much on some websites.
Can't go wrong if they work good for you. Could even change the vanes if you wanted.
