Switching from 135gr. broadheads to 200gr.Here is my set-up now 50lb. HH longbow 66in. draw at 25in.
Arrows are 45/50 spine cut to 27in.What do I need in spine change now??? 50/55???

3F,
Before going to the expense of new shafting you might try shortening the length to compensate for the heavier head. It sounds like you've got a couple inches to tinker with. If you're shooting woodies, maybe somebody with more knowledge than me can chime in here and tell you a ballpark of how much to trim for that amount of increase in tip weight.

Is that 50# at your 25" draw? One thing about wood is it cam take a bit of spine to go pretty heavy up front, especially 200 grains. I'm far from an expert on FOC with wood, I did build up some 250 tipped 5575 GT Trads. You're likely to get a bunch of responses here, your safest bet might just be to call the place you are considering for arrows and talking to them. I called over to Kustom King once because of getting to many different answers/opinions and it helped. $100+ Makes it worth my while to chat to a pro for a few minutes. Just my opinion.

50/55 or 55/60. If you have a fastflight string add another 5lbs.
-
I would do like olddogrib said and cut about a 1/2 inch off of one of your arrows and see how it flies.
-
In my experience, I'd add about 8 lb spine and paper tune. Do you have access to any test arrows? I think you'll like the heavier points.
-
You need to shoot what you have and see if a spine change is needed , or if a simple point change will do it. Try some diferent weight points and let the arrows tell you what to do.

The first thing I would do is to try the 200 grains on your arrows as is. If they are good you are done, if they are a bit off, shorten your arrows as needed. I have seen more guys shooting Hills with over spined arrows than anything under spined. My experience with Hills says that you are over with your 135 heads already. For a 25" draw you could go all the way to 25.5" bop with broadheads. An arrow that is too stiff may appear to fly straight from a Hill, but it will be skidding on the bow and have no forgiveness.
