Hi Fireline and welcome to the MRF.
As Alastair says, plywood is probably the best material for constructing gradients, particularly transitions as it adopts a smooth transition line almost by itself. For the transition I work on a rough 'rule of thumb' and actually do a double transition by rising half the mean gradient over the first 300mm and then going to the full gradient over the next 300mm. This spacing is set by my open grid baseboard system.
So if your mean gradient is say 1 in 50, rise by 3mm over the first 300mm and then by 6mm over the next 300mm. Maintain the 6mm per 300mm until you are 600mm from the summit and then reverse the process by rising only 3 mm over the next 300mm. This does mean that the length of your gradient is actually 600mm more than if you drew a straight line between the two points, hence Alastair's comment about gradients taking more space than you may, at first, realise.
Hope this helps,
Expat.
