Or you could just wait until your mods update to 1.7.10, since that's the stable version of Forge.
Sadly not true. Forge 1.7.10 is still in development and buggy, they even warm you when you launch it.
The only "Stable" recommended version of Forge for 1.7.x is 1.7.2 Minecraft.
As for today 1.7.2-Recommended 10.12.2.1121
That's why I see no point on going to 1.7.10 (Not keeping 1.7.2) as in 1.7.10 there are not much Mods yet, and all of them are running on unstables buggy versions of Forge.
