Mcmillan A5 comb on Savage actions

I am keen on a A5 Mcmillan for a 6.5/284 Savage 116 but I am not sure whether I am likely to need the adjustable cheek piece.
I have a Mcmillan STC stock 14.5" LOP on my owner built 10/22 and find that with a Premier 4.5-14x50 thats sits within 1/8" of the 0.940" barrel that the comb height is perfect for me.

On an A5 with a IOR 6-24x50 and sloped base (probably 20moa) is the standard comb likely to be high enough or would I need to go to one of there adjustable types.
If yes which comb is preffered and why? I have made a thumbwheel adjustable comb on my 77/44 that has a big fat suppressor on it to get my eye to line up with the stock.

Thanks guy's

You coule measure the centerline of your scope on both rifles and compair to the comb rise and see where they all fall out.
I use some by Cheek-eze ? it is a dense foam that covers the comb it comes in several thicknesses (if thats a word) and could raise you comb about 1/2" or so , I put the 1/8" on all my guns cause it makes the hard kickers a little softer on the cheek bone.
But then again , I like to have adjustable combs on all my guns so I can taylor them to fit me , a good cheek weld is a very important part of accurate shooting

Order the stock without and then add a saddle type from McMillan later if you need to.

Given the option when buying new I would get the built in adjustable. Reasons as follows,

1. Murphy says if you don't have it you'll need it.
2. If you need it and get a stock pac, you will have to take your stock pac off every time you clean. Even if your careful it wont go back in the same place twice.
3. The lock nuts on the Mac stocks are very good and you can mark the cheek rest for your position. That way when you drop it to clean you can go back to zero.
4. Thumb wheel is an expensive option but works exceptionaly well if you get the removable cheek rest option.

Proper eye relief is paramount, it's just how much pain you wish to endure getting it there.
