Hi guys, so i have been reading up a lot over the past month or so and have decided to make the jump to a 4 mill. So here is the big question that i would like to get some input on, are the Serval cub cylinders really worth the nearly $300 difference in the LP Driveline cylinders? I understand that the Serval cub is a more proven setup, but from the very few topics i could find over Driveline cylinders the numbers looked pretty close. Any input is appriciated, i am just trying to educate myself before i go a drop that much money.
