GRB aircraft SP/custom load out rework

I think the those guide weapon should drop the SP cost as well, like KH23… most of times they are worse than big rockets like S25O or S24. And we should consider the discount of the SP, when most of planes has agm65B or D at the BR, if some plane like AJ37/AJS37 only has AGM65A, the SP cost should reduced at least 10-20%

True. Wonder about having the cost change based on % of belt being the highest penning round.

Higher tiers can get a bit iffy because some munitions are better depending on who you ask. The biggest example would be TV guided vs laser guided weapons. They both offer specific pros and cons. I would probably lean on having them both be the same SP cost.
I too am not very experienced in helis but I am sure we can get a heli player to give us some good insight.

I am fully down for that. Some sort of discount for heavy bombers. Would also provide some nice, large targets for spaa players.
