I like the Molnar stuff as long as he has it in stock. You have to use the correct main seal with the Molnar crank. If Molnar doesn't have any cranks in stock then my next choice is SCAT. SCAT typically wants a different rear main seal than Molnar but you have to inspect first since it isn't always the same. K1 also makes good cranks but they don't have a super big selection. Nice thing about K1 is that they are owned by the same folks who own JE so if you are a dealer you can sometimes bundle up a K1 crank and rods with JE pistons and get a good price.
