Thank you for your replys. I have come to the decision to go with the grease hubs. The reason I'm going for grease is that you could wind up with the same tear or hole on the seals causing a leak. If a leak happens in an oil bath system and the oil drains out the bearings will not have any lubrication and grease will still remain on the bearings and not leave you stuck on the side of the road with a burnt up bearing.
I do like the idea of the maintenance of the oil bath system, but you do need to keep a close eye on them to insure that you don't get a leak and lose the oil. Also keeping the temperature down on the longer trips.
No one, I've talked with could say one is better than the other, but I'm more familiar with grease hubs. So I guess thats why I made the decision I did.
Thanks again for your comments and I hope this can make someone else's decision easier.
