What is the best map at LHC in terms of EXP per Monster?

From what I've tried out, it seems that Bearwolves have the upper hand.

Last night I did an hour with my guildmates (14x Shad, 18x BM, 18x NL, 16x Bishop for HS mule, & 11x afk mule for bonus exp, plus myself [195 BM])

The result: 8.5% in an hour with a 1.5x exp card (didn't use my 1.2x buff b/c I had used it earlier that day).

I am almost positive I was getting about 7-7.5%/hr at castle golems with the same party.

The castle golem map is still really good because, as stated previously, it's a tighter map so you don't have to move around as much to attack, however, I did not find much trouble moving around the Bearwolf map we were on since I had haste (I think it was Under the Castle Walls 5? not entirely sure though...it had 3 raised platforms and the bottom platform).

Very Tall Castle Walls seems to be the best map for Golems.

For me personally, castle golems are major annoyance, because my Freeze stand isn't high lvl enough to avoid super kb effectively.

EDIT:

Would crocs be better than Bearwolf and Castle Golem for me? It seems the kMS English community training there at 12X-14X. Is it just that kMS has golem/bearwolf maps full?
I lose most of the exp to the higher levels when I'm at bearwolf/golem.
