KR> VW Crankshafts now stronger for heavier props?

[Chris Prata]

GOAL:  A three blade ground-adjustable for my VW KR1 build
In my prop thread, someone mentioned crank strength and breakage using anything 
but a light wooden prop.  My understanding is that these newer VW's (revmaster, 
AeroVee, GP) have gone to much stronger, custom forged crankshafts, and add 
crankshaft length and a thrust bearing to the snout (prop) end of the crank. 
QUESTION: Are there still issues with crank breakage using heavier adjustable 
props on these new, stronger cranks?
