Jason, I like to keep the speed at 270 fps or under. I used the Modoc's for a while and they tend to fly the best however the blood trails are a little week. If you use the cut on contact 2 blade I would suggest using one with a bleeder blade. I shot Muzzies last year and they worked fine at around 270 fps, but I had a great tune on the bow. I would make sure that if you go with the goldtips that they are spined correctly for your set-up. If I can remember correctly you had a longer draw length. I shot the LX last year and found that the carbon express terminators worked real well. The terminators are a little heavier than most. Not trying to sell you on another arrow or anything, I am just not too familiar with the gold tips and their sizes. You might want to do some home work on arrow weight to make sure that you get the perfect combination. With todays carbons there are a huge variety of types and sizes to choose from. Remember in our conversation that we spoke of pin point accuracy and confidence that carries over into hunting. I beleive that a slightly slower arrow that is more forgiving is better than speed any day.

Jason, I have looked at the switchback and did a little calculating. I feel that an arrow pushing closer to 500 grains will put you in the ballpark. You have a long drawlenghth and the switchback is quick. I was shooting 270 fps from my LX with a 514 grain arrow. That calculated to 83 ft lbs of kinetic energy. Way more than enough for elk and probably enough for griz. Put a cut to the tip broadhead on it and that elk will be like shooting through butter. The long draw length is definalty a plus when setting up an elk rig. Becuase of the higher energey, I went back to a 3 blade because penetration was not a factor for me, but an extra wound channel and good blood trail was.
