+Atk H!Henry Gronnowl Refinement

I have a +Atk/-HP H!Henry+3 who I run with Gronnowl+ and Close Counter and am trying to decide which weapon refinement to get. In a 4 armor team I usually have Hector with Goad Armor and 2 others with Ward Armor but when I use an armor trio it's typically without the Hector.

I'm deciding between +2 Spd vs. +3 Def. At 35 Spd + 2 (ally support) + 4-6 (adjacent allies) = 41-43 he's right around that point where he can double many of the fastest units. I'm thinking to give him +Spd so I can free up his B slot to run either Renewal or Vantage but worry about missing out on some critical KOs. In particular, he may miss the double on B!Lyn and there's also the prevalence of green mages running G Tomebreaker but he mostly won't be battling those. Negating Effie/H!Jakob's WF is nice too. So of course the alternative is to keep QR and just go with +Def.
