Yeah ive thought of it, however ive landed on a mod called HighLands (i also got perms for that mod):

Right now testing out a mod that got released a few hours ago, made by the same guys that made the dinosaurmod (sorry but cant recall the name right now) and that is a mod i hope to include in the 1.5.2 update. As for the update itselfe the current mods arent fully updated to 1.5.2: MystCraft, UE with addons. What used to be called Soma and Fauna is now renamed Natura, thats also in the testpack. Same is Lord Of The rings mod, both the new mods are working great.
Im also thinking some about Metallurgy and Galacticraft, but I havent gotten around to sort out the perms yet, or tested compability (ive been told Galacticraft have some issues with Inventory Tweaks).
And at last, im working on upgrading the server. More ram etc so it might be even more stable. However, as always, funding _is_ an issue still ... (serverrent isnt going up, even with the upgrade)
