German pilsner malt for example is good to mash in at 55c for 15 mins .
English malts , don't mash at 50c . You'll lose head retention and protein damage .
To get a good bodied beer full of maltiness , mash higher . 68c to 72c , I'd do 70/71c myself . But you want some dryness to the beer ( if not use less hops to get sweeter ) you may be better doing a small rest at 60/64c , i'd do 63c for 15 -30 mins . More for drier .
If wanting to mash higher temp don't over do the lower rest ( like 60 mins as it'll be too late and finished)
Then finish off at 71c for 40 plus mins , use iodine to check if mash complete .
You'll most likely get better efficiency too , poss 5% .
Try it for a batch and let me know what you think .
