[Fot] Key question

[Philip Gott]

Hi all;
I’m thinking of ordering a billet crankshaft.   Am wondering if anyone has had one made with a single long keyway in the nose instead of two woodruff keys. Are there any durability/stress riser/fatigue  or other downside issues with a long single keyway? It would make assembly of the front pulley onto the crank so much easier if/when it has to be done in the car (which we’ve had to do several times). 
Phil
