How much money do you have to spend?I have a friend that was in the same position as you and wanted a 4mm Cub but he didnt want to save up money so he just spent what he had and got a-rms and carbs.He is way happier.Me on the other hand am just going to do a 4mm or 7mm stock cylinder this year with all the other stuff and next year a 4mm or 7mm DM cylinder.
