Hi Gents, Had to join just to jump in on the discussion. If I may piggy back on the OP's inquiry...
I am shooting TX-5 26"DL (T-Rex Arms, haha), DW is probably around 63-65lbs (havent tested it, started at 60 then went up several cranks). I got on this buzz with the Ashby Foundation and Ranch fairy. Their logic seems legit, heavy arrow, high FOC, and a fixed blade. Ranch Fairy has sent me soo many pictures of people shooting 40-60lbs with his recommended arrow setup getting complete pass-throughs on all kinds of large animals.
That being said, and too many hours watching comparison tests on youtube, I decided to purchase some SIK F4's and SK2's. I just recently shot both with my new arrow setup (about 521-522grains w/broadheads). The both shot very, very close to each other and about 2-3" to the right of my field points (could be user error there).
I noticed two things when shooting them both, 1) the SK2 actually penetrated further than the F4. this surprised me. 2) I noticed a slight "whistle" when I shot the SK2.
So my question is, if anyone has shot the SK2, have you noticed any whistle and/or noise when shooting. Also, do you think I may be able to get a pass-through using the SK2 with my shorter fps (DW/DL)?
If anyone has shot the F4's how do they fair in weather?
I'm ramping up for my first BIG bow hunt, traveling to Michigan from the Carolinas to hopefully hit a big boy on the edge of a cornfield where wind can kind of kick up sometimes.
Just trying to get more info from people who have shot either...
As a side note, I loved the testing results from the QAD Exodus 125g's too. It sucks that not many peiople have taken the F4's and SK2's through the ringer like other brands. From what I have seen, I happy I purchased both of the SIK's.
