I'm going crazy!   broadhead/field point.   Went so far as taking one of my arrows and stripping the fletching off of it.
Started at 3 feet and went out to 10 yards and it's right on the money!  again.. no fletching

Broadheads are about an inch low and 2 to the left.   

Never had problems before...  just threw a broadhead on spun it to check and golden..

set the bow down for a while and go back later, your getting frustrated. try moving back to 20 bare shafting. if you get it on at 20 your gonna be pretty good in most hunting situations.

What fletching?  How is it fletched (std. helical, max helical, offset)?  What's your FOC%?  Typical of Hoyt and new strings to get a small amount of high/low - easy to fix.  Left/Right on the otherhand might be a bit more difficult if it's spine related.  Broadhead alignment is a 1 in 1,000 problem.  I would never worry about that.  Might try swapping the arrows and see what happens.  If it reverses you have some spline or nock related issues.

Could make life real easy on yourself and just get a Bowtech.

Another common thing guys run into after getting a bad group first try out of the box.  The more you try to "See" what's going on the lower left you shoot (right handed).  Concentrate of full back tension at release and follow through to a count of three without trying to watch the arrow flight.  Sometimes it will surprise you.

Most Hoyt cams like to be tuned ever so slightly advanced in the upper cam.  Not so much that you can feel a double tap on the draw stop, but advanced.

Tried over several days.  Thinking it was me, but my field points are consistent, and frustratingly the broadheads seem to be doing the same thing.  (Low left)

Will look at the cam timing.   

Thank you for your suggestions.

Broadhead alignment makes a huge differnce.  Tuned arrows are clutch for hunting.

Sorry full helical, blazer 4fletch, whisker biscuit, using Beman 340, 26.25" shafts,100gr tips.  Same as I've always shot. 
Ill get my wife to watch the cam timing for me.

I'm assuming ICS Hunter (non-camo) shafts?  Should be good there!  A little stiff and not Washington legal for hunting, but should be 10.1 or 10.8% FOC depending on how new the ViBrake insert is.  Not bad at all.  I'm also going to assume that this is the same bow you were shooting both perfectly with before the string change.   So if nothing but string change happened you can throw out all things related to arrow, broadhead, fletching, FOC, rest contact, etc.  If those things were good before the new string they should be good now.

Cam timing, yoke balance, draw weight, nock height and serving diameter would then be the things to concentrate on.  A lot of shops get in a hurry this time of year and forget to measure nock height and poundage before installing the new string.  Pretty hard to get them back exactly like they were if you don't measure it first.  Once you get the yoke balance and cam timing verified I'd try French or Walk Back tuning (modified French method).  I find it more reliable than bare shaft and/or paper.

I expect it will be pretty simple once you get the timing and yoke good.  Might take 100 or so shots to get that string settled in too.  So I would put those shots through it before you take it to a shop for timing if needed.  Good luck!

The camo hunters aren't legal?!  They weigh in at 417gr and my pull is 68lbs.
 
I will check out the French method and go from there.
If that doesn't work I'll take it back and ask Bill to do the work. 

Thank you!

Well I figured that might be the case.  That's why I said, "I'm assuming ICS Hunter (non-camo) shafts?"  Sorry my assumption was wrong.  Camo Hunters @ 68# - Nice!   That even gives you some cushion.  Though then the FOC is less than 10%.  Could get a little squirly in wind or rain.

Other than that sounds like a pretty darned good setup.  Probably just a simple timing and yoke tune and you will be right back where you were.
