I would prioritise Stiff-Legged Deadlifts (with a barbell) over hamstring curls, which fall into a similar boat as dumbbell side-raises.
You would be far better barbell squatting using your bench-uprights as a squat rack, if this is possible.
My diet is pretty good, i dont calorie count or log everything but a good day i loosly follow a pretty good bb diet (tuna, eggs, cottage cheese et cetera). In the past i have usually just had a tuna sandwhich with loads of tuna post workout, but i will get some whey this week.
i suppose ultimately if you are gaining well then you can stick to what you are doing. A time will come though when you have to get a bit more rigid with what you eat
Any advice that can be given on my split is appreciated
