I have the fluted match .243 and a semi weight in 7mm for my R8 and a standard .270 on my R93 all will shoot better than I can.
Buy what you like and enjoy it, it's easy to add more at different weights as pocket allows.

i can swap between the .243 fluted match and the 7mm semi weight and it doesn't seem to make any difference.
The R93 .270 is the success thumb hole and is just sweet to use.
How does the weight/balance feel across the 3 of them ?
The length is calibre dependant semi weight 58 cm match 60cm or 65cm for both though the semi has optional shorter length at cost just google Blaser barrel and open the pdf

Now you're into a whole new debate of what length barrel for .308 and there are probably several previously written threads on here.
you would have to speak to a Blaser dealer for the difference in weight between the mentioned lengths and then the mod you use will change the feel.
i have the ASE ultra on mine as being heavy stiff barrels I didn't feel any change in balance with them and less so if they were shorter.
Then the dent to your wallet and the delivery time for the options.
outside of weight, would a shorter barrel not be less accurate over distance than a longer one ? I like the idea of a shorter barrel but conscious that accuracy on distance (say out to 200 yds) could be compromised
Why would it be less accurate?
