I like the 125gr. Snuffers, but I also add weight behind my insert and end up with an effective weight of 198gr. up front. Mainly I stick with those because I like the way they fly and easy to sharpen, I also didn't want to buy all new broadheads. I could switch to 160's and get by with less weight behind the inserts, but it was an easy enough fix. You can shoot whichever broadhead you want to and adjust your weight behind the insert to whatever you need to get your spine right for your set up.
I recommend using Stu's calculator cause it was spot on for my set up, just get the values as close as you possibly can and don't fudge on anything by guessing. It works amazingly well.
