Oliver,
I made it 3 minutes and my internet connection stalled out. How acorns falling on the roof of the building you are in becomes an excuse to call your neighbor a butt hole is puzzling.
Those Stihl bars for the 3005 mount use drive link count of 44, 50, 55, and 61. At least in the 3/8 picco. Of those only the 44 is divisible by 4. the 55 ends up with two cutters the same way and a skip. If you got a universal mout or modified a brand x you could run a balanced 56dl loop and have the sprocket to bar tail as designed, Stihl puts the oiling input hole far back and high so most brand x are not suitable for such mod. The Stihl bars can better be modified for brand x that usually come stock with a 7 tooth nose as opposed to the 9 tooth for the 63 class Picco.
What would be informative (besides the actual weights in the text here) is clamping the tails of the two bars say a block of wood above a bench top or similar and then adding weight to the nose and noting the deflection difference..
