Slotting WP build for Regen

I have recently gotten my Stone/WP brute to 50. He was one of my funnest toons to level up and I recently came across some very lucrative drops so I have decided to try to upgrade many of his IOs. Since he is WP, I've tried to enhance his HP, regen, and recovery. To this end, I've 4 slotted both QR and Stamina with 4 Perf Shifters (End Mod, 2 end mod doubles, and the proc) and that seems to work well. I'm now examining the Regen side of the house and was seeing some odd things in Mids.

In the legacy build, I had 3 slots in both Health and FH and 4 dedicated to Heal recipes in RttC. I left that alone for now and had this:
FH: Numina: Heal, Heal/???, +Regen/+Recovery
Health: Mircale: Heal, Heal/???, +Recovery
RttC: Regen Tissue: Heal/End, Heal/End/Rech, +Regen; Dark Watcher: To Hit Debuff, To Hit Debuff/End; Generic Heal IO

The +Regen "procs" seem to actually be lowering my overall regen. Replacing them with Heal IOs seems better in Mids. Does this sound accurate? Those are very expensive recipes so I'd obviously rather save the money if the numbers are close.

If so, which of the following strategies should I go with:
1. Just forget the procs and go with the 50 Heal IO (I would also lose a +HP set bonus)
2. Get rid of the Dark Watchers from RttC. (I would lose +HP set bonus and ToHit debuff, which I like)
3. Find another slot for both FH and Health and get the other Heal/??? double from the respective sets in there. This will get me closer to ED cap and then the regen or recovery bonus is applied on top of that.
4. Find another slot for both FH and Health and add a 50 Heal IO to be sure to get regen near ED cap.

For 3, I would also get a set bonus to "Heal Enhancement". Are these set bonuses like Heal enhancements and triple as Healing (adding hit points back all at once), Regen (speeding up the rate at which you gain them back over time), and raising maxHP? I don't have any true Healing powers so I'm trying to see if Heal set bonuses would help at all with Regen and my raised HPs.

Sorry to be so verbose, but in summary, I want to know if changing my Heal IOs to the expensive sets is really worth it. Other folks seem to swear by these sets, but the numbers just aren't looking as good as I'd hoped in Mids.

Any help with this or other suggestions that may help this build are appreciated.

Thanks,
King

All players welcome!

you'll actually be more survivable by adding more defense and +hp to your build than just +regen.

Getting the the hp cap is important and accolades help that alot.
As far as the uniques go, they work well when slotted into a power IN ADDITION to normal +heal slotting as opposed to INSTEAD OF.

I typically 6 slot FH with the 3 uniques and then 2 numina IOs and one common heal IO.
Then I'll 3 slot health with 2 numinas and 1 common heal IO.
