Whew... Lots of questions. Yes, there have been failures with welded cranks. Know the reputation of the one installing the weights. Dan Price makes sweat-on weights that are similar to the BB crank. The issue I see with those modifications is finding a crank that is not already been machined too far undersized where the effort in counter weighting is short lived. Is it overkill to move ahead with purchasing the SCAT crank? IMHO the answer is "No". The SCAT crankshaft is a very nice piece, and while it is not for everyone, the mass weight and modern technology really make a nice unit. I would have this chat with your (experienced) engine rebuilder to get his opinion too.
