New Gathering nodes

[LudvicStone]

As someone who has supras on all 3 gathering classes, when I heard about the new main hand tools coming I knew I would need to increase some aspect of my gear to have a better chance at them
luckily the only thing that isn't fully melded at this point are my offhand for miner and bot.
Both are at 452 gathering and 442 perception with the only things not melded are the i70 off hands i have for both of them.

Now onto the issue, we need to gather 99 HQ antumbral rocks and 99HQ redolent logs, going off of the assumption that bother share the same requirements for getting them, I am going to say at my current gathering I have a 84% chance to obtain the rock/log itself and a 4% to get a HQ rock/log

So now I come to my fellow gatherers, what should i meld my offhands with, and how should I be going about opening up these nodes, wasting the 2 strikes at the start to open them up so i have the 600 GP for increase both my gathering and perception? or should i use toil of the mountaineer?

EDIT: sorry i named the thread wrong I meant to say "new gathering tools" not nodes
