I have the first one, but I'm not sure where you got those two IF points from. At lvl31 you'll have 0IF and lvl32 will give you three. I have my wpf split the other way though, 150 throwing, 118 2H. Fun build that allows kiting from almost anything. After the recent nerf to throwing speed bonus cavalry is a huge problem though and needs to be avoided as you can't kill them.
With 4PT you'd have worse throwing weapons, so I wouldn't go there. 18/21 could be a good option as well.
Edit: Wait, did you want a 2H hero or a 2H thrower? That 15/24 works fine as a 2H thrower if that's what you want. 5PT, 5PS, 5WM, 8ATH at lvl30 and 8WM at lvl31. 2H agiwhore you could try 12/30 with 10 athletics, 3WM and 4PS.
