Get a classic.
Look better and they are lighter
Id say a HD axle and fun bolts are worth the investment from the off, not had a single problem with either. A steel driveshell is also another must.
As for the skipping-ness, Id be inclined to say get it built up, ride it in for a few hours and see what its like first before burdoning adam. For one it might not need fettling and two, if it does need messing with, you might aswell get some bedding in done and THEN a fresh lube done
