Alright thanks so much for the help guys, I'm going Sugizen chainring, Sugino 75 crankarms and deciding between the normal Sugino 75 BB, Hatta Swan R9400 and the Sugino 75 BB Superlap.

Should I go with the Superlap BB/consider the Hatta R9400? Or are they just overkill, and the normal Sugino 75 BB is good enough?

Also should I change my pedals? I don't exactly have much problems with my current pair (Wellgos with BLB Plastic cages) but I'm wondering if changing to MKS Sylvan Tracks will make it smoother spinning. Or is it another case of overkill?

Thanks a lot guys.
