Got my hands on a P upped Buriza, now it is time to put this beast to use! Still not sure about some item slots though, so looking for some feedback from the off-meta specialists

Weapon: Buriza upped
Gloves: 2Bow/20ias/14str for start, will do some crafting in the hope of getting 20ias/10cb/adds
since Buriza has 80ias clean, i reach the 95ias BP with just the 20ias from gloves. there is another minor BP for strafe at 105ias, but that only removes one more frame for the last arrow, so i wont commit to that. thus, i dont need more ias from any of the gear!
Amulet: Atmas. i will use multi and strafe as skills (so mostly physical dmg) and dont need ias from this slot, so Atmas seems best to me with ctc amp
Belt: 30str/some res for start. maybe going to try some blood belts, will see
Armor: Forti dusk. dmg and resists, perfect combo
Boots: Gores
Ring #1: Raven
Now to the flex spots:
1. Buriza socket
option 1: ed/-req jewel. would save 35 stat points to str/dex if i calculated correctly, so roughly 100life. would also imply to use lidless/splendor on switch instead of spirit (-1 lvl BO), not that big of a deal
option 2: Ber rune. CB only works at half effectivenes for ranged weapons, with Gores and CB gloves this might be over the top
option 3: Lo rune. second source of double dmg with crit strike, might be better than Ber against bosses
2. Helm
option 1: Gaze. dual leech (which gives higher flexibility on the second ring slot) and physical resist. could be socketed with an Um rune for some more resists
option 2: Giant Skull. good boost to str, some CB, knockback (definitely not necessary, not sure if useful), 2sox for maybe Um runes
option 3: Kiras. solves the resist problem on its own. socket probably ed/dex jewel? also grants CBF; this gives flexibility on first ring slot, but raven is already a good ring for Bowzons... resist rings would also not needed anymore, so only stat rings/dmg rings would be useful
3. Ring #2
option 1: min or max dmg. always good to have
option 2: stats. translates to a life bonus, but only 3life/stat point (so 20 stat point ring equals 60life)
option 3: resists. no shield and not much resists from other gear slots
option 4: BK for life leech and +1 lvl BO
not willing to spend much fgs, will try to work with what i have. thx for all suggestions
