Chris -

Do you know what the pay outs will be for the new LLSS class? Do you have any pullers all ready committed to running with WTPA? I would like to here more from WTPA about them adding this class like why they have decided to add it. What the benefits are to pull WTPA instead of other organizations in the state. With a higher initial cost to join and pull WTPA rather than other organizations in the state why should people come to WTPA or build for WTPA? I'm not trying to start any war or bashing on this subject from anyone. I just think people would like to hear more from WTPA about this addition and what they have to offer being there is already 2 other LLSS classes in the state.

Thank you

I can give you the reason we are signing up with wtpa, up in the northern part of the state we don't have a llss to pull in. If we wanted to pull with a org. In the past, it would have meant driving to the southern border of the state for basically every hook, of course we'll have to travel some with wtpa, but at least there will also be hooks up in this area!

What would a step down housing or wheel be. Would a clipped wheel be a step down?

Those rules will make for a very broad range of tractors. VERY NICE Drinking
Will be nice to see that class offered. WTPA needed another class to offer promoters. Thumbs Up
Its nice to see organizations running the same rules.
The sand box is very large and it offers more places for pullers to go.
LLSS is a growing class in Wisconsin all over the state.

Will this class eventually bump the single charger diesels to a 3.6 inlet like the southern groups have done, or isn't that necessary? Are the diesels able to keep up with the alkies in Badger State?
