Kosh, the main argument I have seen for keeping the faster twist is that monolithic bullets seem to open quicker when spun faster. Bullet stability is largely dependent on the RPM's of the bullet, so the speed the bullet is traveling when it leaves the barrel comes into play. The .243AI muzzle velocity is significantly higher than a 6mm ARC, so the ARC will require a faster twist to stabilize the same bullets.
If you go with a relatively slow twist barrel, please report back as to its performance, especially with 105's. Thanks
