SS you asked for opinions regarding Treesharks & VPA.
Since you are using a 38# bow, I stand with my original opinion regarding using only a very sharp cut on contact 2 blade broadhead.
From my experience, 3 cutting blades will slow down and or reduce the penetration into the animal.
Same with using the wide and Curved TS.
It is my opinion You do not have enough umph to properly push those broadheads through and into a deers vitals.
Sharpening the TS looks to be a PITA for accurate angle sharpening along that wide curve.
Personally, I prefer using simplistic, easy to sharpen, tried and true equipment.
You heard the saying about "Opinions", everyone has one... This is only my opinion.
Again, since you are using a 38# bow, I stick with my original advice on using a very sharp, cut on contact, 2 blade broadhead.
In my opinion, and again, It is just my personal opinion that many broadheads are just being marketed like fishing lures... to appease to the inexperienced bowhunter by using the look of coolness, look of dangerousness, using a wow factor of the cutting blades, etc,
In reality, using wide and multi blade broadheads have less penetration than a simple 2 blade cut on contact, of known, proven proportional dimensions.
