Lasalle a solo re-try

On a whim I decided to give Lasalle rules a run out (despite having several untried sets !) using my Prussians (bought and based for Lasalle) against my French.
Forgot what a slick fast playing set they are.
But as always I came up against the 'phalanx' problem wherein two Infantry units in Attack Column ('phalanx') simply run over Infantry in line as they generate double the dice generally.
Tried a couple of house rules such as extra dice for Line shooting but best I came across was if Attack Column suffers a Disruption it must form Line with possible consequences on neighbouring columns etc.





Several pics as I played this over several days as time at a premium at present...........
