Ask your clan. Personal experience, but before my account got fuxxored, the guys who were requesting every 20 minutes like clockwork didn't give a shit what they got, but the guys who requested only for war attacks were very specific in what they wanted and who they wanted it from (level wise, anyway).
I was one of the guys who only requested for wars, and I would be pissed if you filled my clan castle with shit and delayed my attack. I was TH8 and only barchlin'd in regular attacks, so if 200 troops couldn't get me some loot, another 20 wouldn't have made a damn bit of difference tbh - that would have been a user error, not a troop error.
On a side note, I miss this game so much... the withdrawals are awful. I actually... work... at work now... it's weird.
