I'm wishing to attempt a Summer Lightning clone using the recipe from GW's book...
However I'll be using Liquid Malt extract and the tins are 1.6kg in size so to use two full cans (and avoid measuring a messy liquid) I have adjusted the final volume and quantities of hops...
the final volume will be 19.5 litre (rounded down from 19.67l)
I will add 40g of the boil hops instead of 38g as stated for a 19litre batch size.
I have decided to only boil one of the cans in 13 litres of water to give me a gravity of approx. 1035-1038 increasing hop utilisation to a point where I can reduce the boil time to 60 mins from 90 as stated in the book.
By my calculations I should acheive a beer with similar (if not identical) Gravity and bitterness by using this method and saving on energy &time.
I plan to add the remaining can of LME direct to the FV and rinsing the can out with the boiled wort or hot water from the kettle (as I would if making beer from a kit)...
then once cool checking the gravity and toping up to the final volume and pitching my yeast (starter).
I welcoem comment and advice (of a constructive nature)....

Many thanks !
Slainte!
