Lookiing for tips on which bow to make my faith on (this is D2R,xbox)

Contenders:

3skill gmb
3 skill matri
Diamond bow

My setup looks like:

GSKULL 2x 15ias jewel (cows/chaos/wsk + baal)
Steelskull 15 ias pit,tunnels,shenk,pindle, edldritch
Fort
Razortail
LOH glove
Travs
Dual leech ring
Raven frost
Atmas scarab (have cats eye aswell)
Harmony (gmb,matri. Working on finding a diamond)

Str for gear
100 vita (750 life)
Rest into dex

Use strafe mainly (maxes), have GA at lvl 15, valk 15, crit strike 15, pen maxed (previously used winforce, will respec), 6 pierce . Will respec when i get faith and move the 19pts from penetrate to multishot,GA, valk

Im leaning towards the matri bow because i can hitn7 frames with just LOH and giant skull or steelskull allowing my to use atmas which tripples my damage.

Than theres GMB, dmg which has a ton more max damage. I could use this and stay at 8 frames and be able to keep atmas on. Also 7 frame isnt an option if i dont roll 15 fanat/ use a 45 ias helm. However thenmin dmg is rather low

Diamond is appealing because i can hit the 7 frame with 65 ias (again giving up atma) . But the diamond has very consistent damage. If i stick to 8 frame all i need is 29ias on gear. This would let me grab a nice rare On circ with res and frw

Ao not sure what route would be the best balance. Again probably over thinking aince I focus on strafe. But having 7 frames is a healthy boost for GA or magic arrow vs immunes or if i wanna do occasional pvp
