I was thinking of doing it similar to OSRS Gold this: Create a thread on the giveaway and then I will ask questions like. Why should I give you a Membership? Why do like Runescape? What will you do with the Membership? These questions will make it easier for me to pick the winner, and to hinder members from selling their codes or to prevent lazy spammers from obtaining the membership.
"Normal" (as it is not Nex) GWD armour is adequate to perform Slayer tasks. It's not a lot of money (for someone with your resources) it doesn't have to be repaired or replaced, and it gives offensive bonuses. Keep a Barrows set that includes every combat style (Verac's, Ahrim's and Karil's) for the few Slayer tasks that require high defence armour.
Glacor boots are the most comfortable boots available. Barrow gloves aren't very well anymore. They're hybrid gloves and do have their uses, however, if I were in your shoes I'd opt for the TWW automation gloves (Static Pneumatic, Tracking, and Static). They're the equivalent gloves to Glacor boots.
Amulet Of Fury remains an excellent amulet, and is the best hybrid amulet , in fact. If you've got money to spend , you might want to purchase a Saradomin's hiss (second most powerful magic amulet behind the Stream Neck), Murmur (currently the best melee amulet in the game) along with Whisper (best for range-based amulets).
Melee weapons if you don't own chaotics. could buy Drygores, they're far superior but expensive. If you're not willing to Buy RuneScape Gold spend the money to buy a new weapon, just use your Saradomin Godsword. (or learn to train Dung and purchase a maul)
