I'll give the Plexus a shot, to be fair and unbiased? But, with no disrespect, I'm probably going to stay with Amsoil's, Mudslinger. Mainly because, I'm an Amsoil dealer, so, I can even get it even cheaper, than the Plexus goes for and without the shipping. Plus, they're both very fine products also. The only reason that I became an Amsoil dealer in the first place, was because all my rides use Amsoil, I also think it's a very fine product too. So, it just made since, for me, to become an Amsoil dealer, instead of a preferred customer. That way, I can save more money in the long run. I've been very happy with all of their products so far. Amsoil is easier for me to get, because they send it, right to my house, within three to four days. I make out an order and I just buy extra supplies for my cars and my bike. Things that I know that I'm going to need. Then I buy them buy them then. Right now, I'm on a cost cutting crusade. So, that I can save my money, to buy those tires that I want and need real soon. I'm buying those Michelin Commander III's Cruising tires. That are going to cost me around 307.00 brand new, for the set of tires in my size. Thay get 25,000 miles on a fully loaded HD Dresser. My Bobber, is a lot lighter than any HD dresser is. So, I should get some real great mileage out of them. Otherwise, I could get some cheaper tires, but I'll only get 12,000 miles out of a set of them. Since I'm on a fixed income, I've really got to watch things very closely right now and hang on to my money, for those metric tools, along with a good torque wrench. That I'm going to buy for my christmas present.
