Winter feeding quandary!

[Fimbacob]

Have noticed these grass replacement nugget type feeds on the market now and was just wondering what people think of them?
Last winter my pony was getting very hungry as we are not allowed to feed hay in the field. YO now gives him haynet in morning before I turn him out, so trying to decide if this is adequate, or whether to feed him a bit extra when weather gets worse and grass is depleted.
Friend suggested alfaAoil but when I read up on it, it says it is for weightgain and I dont want him to put on weight, just not end up starving. He is currently on forage and lo cal balancer as only in lightwork but not overweight.
I know I am probably being a wet lettuce but just want other opinions to help me decide!
Thanks!

My YO uses simple System feeds grass/luci nuts for the stallion and several other horses and they are doing really well on them, super feed IMO. I guess it is like any feed though things work better for others and it is a bit of trial and error but I really rate them.

Thanks Batgirl. I think I have heard of them. Don't they come out and do grass/soil analysis first?
Any other opinions? Is the haynet in the morning enough?

Can he have more hay overnight so that he is not hungry in the morning, it would make more sense than giving extra hard feed, possibly give some in a trickle net or doubled netted so it lasts longer through the night.
Apart from my 2 real fatties mine are fed just about adlib, this includes a 14.2 greedy pony but he never finished his net once he settled and realised it would last.
