Okay RJ, now you've done it. Between you and Misshydro, I had to order both a Pak 20 AND an Eagle kit. I just hope you are both satisfied. Needless to say, neither of mine will be stock when done. Can we say lightened and improved? I'm looking at a K&B .21 for the Pak and my K&B .45 for the Eagle. Either that or go with an OS 18 for the Pak and the K&B .21 for the Eagle. I might have to put the K&B .21 in both, still trying to decide. I figure with as lite as I want to get, any of the above set ups would work. What would be sad is if my Eagle could beat Misshydro's Eagle with mine having only a .21 for power. Any bets on that one
