Adjustment of keeper?

okay so is it possible to adjust the keepers to a full cheek bit "long" or "short" and if so what is the ideal length and what will ensue if they r 2 short/long?
Answers:    If you mean the actual keepers self long or short, then, no, they're not adjustable that way. You CAN adjust the position of the keepers, though.

To catch more control and more leverage on the poll, put the keeper at the top of the spike on the cheek piece of the bit, and attach it to the cheek piece of the bridle just above the connector/buckle thing.

For a milder position, slide the warden closer to the ring of the bit and attach it to the cheek piece of the bridle where the connector is.

In my experience, this does make a difference. But I have OTTBs which may enjoy larger bits.
The keepers themselves don't adjust, but you have a little bit of capacity as to where they hook onto the cheek pieces. My pony's actually have to be down surrounded by the loops of the cheek pieces or else they pop off the tops of the bit. I really don't think the 1/2 to 1 inch difference will form much difference in terms of leverage.
