I use the AG4D 300 regularly, but keep these Euro versions in my bag.
I believe that the 4D 300 has a little more "feel", but I do wish the AG4D had the weight and plow-through of the 16X18.
(I have added lead-tape to the AG4D, but can only get it up to 11.3 ounces.)
I have tinkered with weights on the euro and i have a little at 3/9 and also 12oclock. Easy to work with when specs are bang on. Great QC
